The functions f±g,f g and f /g are defined as follows: (特别注意符号(f±g)( x) 定义的含义)①(f±g)( x)=f(x)±g( x),domain =A∩B②(f g)( x)=f(x) g( x),domain =A∩ B③(f /g)( x)=f(x) /g( x),domain =A∩ B and g( x)≠0Example 6 If f( x) =( x)1/2,and g( x)=(4-x2)1/2,find functions y=f(x)+g( x),y=f(x)-g( x),y=f(x)g( x),and y=f(x) /g( x)Solution: The domain of f( x) =( x)1/2 is [0,+∞),The domain of g( x) =(4-x2)1/2 is interval [-2,2],The intersection of the domains of f(x) and g( x) is[0,+∞)∩[-2,2]=[0,2]Thus,according to the definitions, we have(f+g)( x)=( x)1/2+(4-x2)1/2,domain [0,2](f-g)( x)=( x)1/2-(4-x2)1/2,domain [0,2](f g)( x)=f(x) g( x) =( x)1/2(4-x2)1/2=(4 x-x3)1/2domain [0,2](f /g)( x)=f(x)/g( x)=( x)1/2/(4-x2)1/2=[ x/(4-x2)]1/2 domain [0,2)1.3.3☆☆Composition of functions (复合函数)P45☆Definition(1-3) Composition function: Given two functions f and g the composite func tion f⊙g (also called the composition of f and g ) is defined by(f⊙g)( x)=f( g( x)) (特别注意符号(f⊙g)( x) 定义的含义)The domain of f⊙g is the set of all x in the domain of g such that g(x) is in the domain of f . In other words, (f⊙g)(x) is defined whenever both g(x) and f (g (x)) are defined.

Then its inverse function f -1(y)has domain B and range A and is defined byf-1(y)=x f (x)=y for any y in Bdomain of f-1=range of frange of f-1=domain of f( 注解:it says : if f maps x into y, then f-1maps y back into x . Caution: If f were not one-to-one function,then f-1 would not be uniquely defined. )Caution: Do not mistake the-1 in f-1for an exponent. Thus f-1(x)=1/ f(x) Because the letter x is traditionally used as the independent variable, so when we concentrate on f-1(y) rather than on f-1(y), we usually reverse the roles of x and y in Definition (1-5) and write as f-1(x)=y f (x)=yWe get the following cancellation equations:f-1( f(x))=x for every x in Af (f-1(x))=x for every x in B See Fig.7 P66Example 4 Find the inverse function of f(x)=x3+6Solution We first writef(x)=y=x3+6Then we solve this equation for x:x3=y-6x=(y-6)1/3Finally, we interchange x and y:y=(x-6)1/3That is, the inverse function is f-1(x)=(x-6)1/3( 注解:The graph of f-1 is obtained by reflecting the graph of f about the line y=x. ) See Fig.9、8 1.6.2 Logarithmic function If a>0 and a≠1,the exponential function f (x)=a x is either increasing or decreasing and so it is one-to-one function by the Horizontal Line Test. It therefore has an inverse function f-1,which is called the logarithmic function with base a and is denoted log a,If we use the formulation of an inverse function given by (See Fig.3 P56)f-1(x)=y f (x)=yThen we havelogx=y a y=xThe logarithmic function log a x=y has domain (0,∞) and range R.Usefully equations:①log a(a x)=x for every x∈R②a log ax=x for every x>01.6.3 ☆Lows of logarithms :If x and y are positive numbers, then①log a(xy)=log a x+log a y②log a(x/y)=log a x-log a y③log a(x)r=r log a x where r is any real number1.6.4 Natural logarithmsNatural logarithm isl og e x=ln x =ythat is①ln x =y e y=x② ln(e x)=x x∈R③e ln x=x x>0 ln e=1Example 8 Solve the equation e5-3x=10Solution We take natural logarithms of both sides of the equation and use ②、③ln (e5-3x)=ln10∴5-3x=ln10x=(5-ln10)/3Example 9 Express ln a+(ln b)/2 as a single logarithm.Solution Using laws of logarithms we have:ln a+(ln b)/2=ln a+ln b1/2=ln(ab1/2)1.6.5 ☆Change of Base formula For any positive number a (a≠1), we havel og a x=ln x/ ln a1.6.6 Inverse trigonometric functions⑴Inverse sine function or Arcsine functionsin-1x=y sin y=x and -π/2≤y≤π / 2,-1≤x≤1 See Fig.18、20 P72Example13 ① sin-1 (1/2) or arcsin(1/2) ② tan(arcsin1/3)Solution①∵sin (π/6)=1/2,π/6 lies between -π/2 and π / 2,∴sin-1 (1/2)=π/6② Let θ=arcsin1/3,so sinθ=1/3tan(arcsin1/3)=tanθ=s inθ/cosθ=(1/3)/(1-s in2θ)1/2=1/(8)1/2Usefully equations:①sin-1(sin x)=x for -π/2≤x≤π / 2②sin (sin-1x)=x for -1≤x≤1⑵Inverse cosine function or Arccosine functioncos-1x=y cos y=x and 0 ≤y≤π,-1≤x≤1 See Fig.21、22 P73Usefully equations:①cos-1(cos x)=x for 0 ≤x≤π②cos (cos-1x)=x for -1≤x≤1⑶Inverse Tangent function or Arctangent functiontan-1x=y tan y=x and -π/2<y<π / 2 ,x∈R See Fig.23 P73、Fig.25 P74Example 14 Simplify the expression cos(ta n-1x).Solution 1 Let y=tan-1 x,Then tan y=x and -π/2<y<π / 2 ,We want find cos y but since tan y is known, it is easier to find sec y first:sec2y=1 +tan2y sec y=(1 +x2 )1/2∴cos(ta n-1x)=cos y =1/ sec y=(1 +x2)-1/2Solution 2∵cos(ta n-1x)=cos y∴cos(ta n-1x)=(1 +x2)-1/2⑷Other Inverse trigonometric functionscsc-1x=y∣x∣≥1csc y=x and y∈(0,π / 2]∪(π,3π / 2]sec-1x=y∣x∣≥1sec y=x and y∈[0,π / 2)∪[π,3π / 2]cot-1x=y x∈R cot y=x and y∈(0,π)Exercises P 74-85Key words and PhrasesCalculus 微积分学Set 集合Variable 变量Domain 定义域Range 值域Arbitrary number 独立变量Independent variable 自变量Dependent variable 因变量Square root 平方根Curve 曲线Interval 区间Interval notation 区间符号Closed interval 闭区间Opened interval 开区间Absolute 绝对值Absolute value 绝对值Symmetry 对称性Represent of a function 函数的表述(描述)Even function 偶函数Odd function 奇函数Increasing Function 增函数Increasing Function 减函数Empirical model 经验模型Essential Function 基本函数Linear function 线性函数Polynomial function 多项式函数Coefficient 系数Degree 阶Quadratic function 二次函数(方程)Cubic function 三次函数(方程)Power functions 幂函数Reciprocal function 反比函数Rational function 有理函数Algebra 代数Algebraic function 代数函数Integer 整数Root function 根式函数(方程)Trigonometric function 三角函数Exponential function 指数函数Inverse function 反函数Logarithm function 对数函数Inverse trigonometric function 反三角函数Natural logarithm function 自然对数函数Chang of base of formula 换底公式Transcendental function 超越函数Transformations of functions 函数的变换Vertical shifts 垂直平移Horizontal shifts 水平平移Stretch 伸张Reflect 反演Combinations of functions 函数的组合Composition of functions 函数的复合Composition function 复合函数Intersection 交集Quotient 商Arithmetic 算数。

Examples: P 321.2.7Trigonometric functions 三角函数P33⑴f(x)=sin x⑵f(x)=cos x⑶f(x)=tan x=sin x / cos x1.2.8Exponential function 指数函数P34The exponential functions are the functions the form f(x) =a x Where the base a is a positive constant.1.2.9Transcendental functions 超越函数P35These are functions that are not a algebraic. The set of transcendental functions includes the trigonometric,inverse trigonometric,exponential,and logarithmic functions,but it also includes a vast number of other functions that have never been named. In Chapter 11 we will study transcendental functions that are defined as sums of infinite series.1.2 Exercises P 35-381.3 New functions from old functions1.3.1 Transformations of functions P38⑴Vertical and Horizontal shifts (See Fig.1 p39)①y=f(x)+c,(c>0)shift the graph of y=f(x) a distance c units upward.②y=f(x)-c,(c>0)shift the graph of y=f(x) a distance c units downward.③y=f(x+c),(c>0)shift the graph of y=f(x) a distance c units to the left.④y=f(x-c),(c>0)shift the graph of y=f(x) a distance c units to the right.⑵ V ertical and Horizontal Stretching and Reflecting (See Fig.2 p39)①y=c f(x),(c>1)stretch the graph of y=f(x) vertically by a factor of c②y=(1/c) f(x),(c>1)compress the graph of y=f(x) vertically by a factor of c③y=f(x/c),(c>1)stretch the graph of y=f(x) horizontally by a factor of c.④y=f(c x),(c>1)compress the graph of y=f(x) horizontally by a factor of c.⑤y=-f(x),reflect the graph of y=f(x) about the x-axis⑥y=f(-x),reflect the graph of y=f(x) about the y-axisExamples1: (See Fig.3 p39)y=f( x) =cos x,y=f( x) =2cos x,y=f( x) =(1/2)cos x,y=f( x) =cos(x/2),y=f( x) =cos2xExamples2: (See Fig.4 p40)Given the graph y=f( x) =( x)1/2,use transformations to graph y=f( x) =( x)1/2-2,y=f( x) =(x-2)1/2,y=f( x) =-( x)1/2,y=f( x) =2 ( x)1/2,y=f( x) =(-x)1/21.3.2 Combinations of functions (代数组合函数)P42Algebra of functions: Two functions (or more) f and g through the way such as add, subtract, multiply and divide to combined a new function called Combination of function.☆Definition(1-2) Combination function: Let f and g be functions with domains A and B. The functions f±g,f g and f /g are defined as follows: (特别注意符号(f±g)( x) 定义的含义)①(f±g)( x)=f(x)±g( x),domain =A∩B②(f g)( x)=f(x) g( x),domain =A∩ B③(f /g)( x)=f(x) /g( x),domain =A∩ B and g( x)≠0Example 6 If f( x) =( x)1/2,and g( x)=(4-x2)1/2,find functions y=f(x)+g( x),y=f(x)-g( x),y=f(x)g( x),and y=f(x) /g( x)Solution: The domain of f( x) =( x)1/2 is [0,+∞),The domain of g( x) =(4-x2)1/2 is interval [-2,2],The intersection of the domains of f(x) and g( x) is[0,+∞)∩[-2,2]=[0,2]Thus,according to the definitions, we have(f+g)( x)=( x)1/2+(4-x2)1/2,domain [0,2](f-g)( x)=( x)1/2-(4-x2)1/2,domain [0,2](f g)( x)=f(x) g( x) =( x)1/2(4-x2)1/2=(4 x-x3)1/2domain [0,2](f /g)( x)=f(x)/g( x)=( x)1/2/(4-x2)1/2=[ x/(4-x2)]1/2 domain [0,2)1.3.3☆☆Composition of functions (复合函数)P45☆Definition(1-3) Composition function: Given two functions f and g the composite function f⊙g (also called the composition of f and g ) is defined by(f⊙g)( x)=f( g( x)) (特别注意符号(f⊙g)( x) 定义的含义)The domain of f⊙g is the set of all x in the domain of g such that g(x) is in the domain of f . In other words, (f⊙g)(x) is defined whenever both g(x) and f (g (x)) are defined. See Fig.13 p 44 Example7 If f (g)=( g)1/2 and g(x)=(4-x3)1/2find composite functions f⊙g and g⊙f Solution We have(f⊙g)(x)=f (g (x) ) =( g)1/2=((4-x3)1/2)1/2(g⊙f)(x)=g (f (x) )=(4-x3)1/2=[4-((x)1/2)3]1/2=[4-(x)3/2]1/2Example8 If f (x)=( x)1/2 and g(x)=(2-x)1/2find composite function s①f⊙g ②g⊙f ③f⊙f④g⊙gSolution We have①f⊙g=(f⊙g)(x)=f (g (x) )=f((2-x)1/2)=((2-x)1/2)1/2=(2-x)1/4The domain of (f⊙g)(x) is 2-x≥0 that is x ≤2 {x ︳x ≤2 }=(-∞,2]②g⊙f=(g⊙f)(x)=g (f (x) )=g (( x)1/2 )=(2-( x)1/2)1/2The domain of (g⊙f)(x) is x≥0 and 2-( x)1/2x ≥0 ,that is ( x)1/2≤2 ,or x ≤ 4 ,so the domain of g⊙f is the closed interval[0,4]③f⊙f=(f⊙f)(x)=f (f(x) )=f((x)1/2)=((x)1/2)1/2=(x)1/4The domain of (f⊙f)(x) is [0,∞)④g⊙g=(g⊙g)(x)=g (g(x) )=g ((2-x)1/2 )=(2-(2-x)1/2)1/2The domain of (g⊙g)(x) is x-2≥0 and 2-(2-x)1/2≥0 ,that is x ≤2 and x ≥-2,so the domain of g⊙g is the closed interval[-2,2]Notice: g⊙f⊙h=f (g(h(x)))Example9Example10 Given F (x)=cos2( x+9),find functions f,g,and h such that F (x)=f⊙g⊙h Solution Since F (x)=[cos ( x+9)] 2,that is h (x)=x+9 g(x)=cos x f (x)=x2Exercise P 45-481.4 Graphing calculators and computers P481.5 Exponential functions⑴An exponential function is a function of the formf (x)=a x See Fig.3 P56 and Fig.4Exponential functions increasing and decreasing (单调性讨论)⑵Lows of exponents If a and b are positive numbers and x and y are any real numbers.

Then its inverse function f-1(y)has domain B and range A and is defined byf-1(y)=x f (x)=y for any y in Bdomain of f-1=range of frange of f-1=domain of f( 注解:it says : if f maps x into y, then f-1maps y back into x . Caution: If f were not one-to-one function,then f-1 would not be uniquely defined. )Caution: Do not mistake the-1 in f-1for an exponent. Thus f-1(x)=1/ f(x) !!!Because the letter x is traditionally used as the independent variable, so when we concentrate on f-1(y) rather than on f-1(y), we usually reverse the roles of x and y in Definition (1-5) and write as f-1(x)=y f (x)=yWe get the following cancellation equations:f-1( f(x))=x for every x in Af (f-1(x))=x for every x in B See Fig.7 P66Example 4 Find the inverse function of f(x)=x3+6Solution We first writef(x)=y=x3+6Then we solve this equation for x:x3=y-6x=(y-6)1/3Finally, we interchange x and y:y=(x-6)1/3That is, the inverse function is f-1(x)=(x-6)1/3( 注解:The graph of f-1 is obtained by reflecting the graph of f about the line y=x. ) See Fig.9、8 1.6.2 Logarithmic functionIf a>0 and a≠1,the exponential function f (x)=a x is either increasing or decreasing and so it is one-to-one function by the Horizontal Line Test. It therefore has an inverse function f-1,which is called the logarithmic function with base a and is denoted log a,If we use the formulation of an inverse function given by (See Fig.3 P56)f-1(x)=y f (x)=yThen we havelogx=y a y=xThe logarithmic function log a x=y has domain (0,∞) and range R.Usefully equations:①log a(a x)=x for every x∈R②a log ax=x for every x>01.6.3 ☆Lows of logarithms :If x and y are positive numbers, then①log a(xy)=log a x+log a y②log a(x/y)=log a x-log a y③log a(x)r=r log a x where r is any real number1.6.4 Natural logarithmsNatural logarithm isl og e x=ln x =ythat is①ln x =y e y=x② ln(e x)=x x∈R③e ln x=x x>0 ln e=1Example 8 Solve the equation e5-3x=10Solution We take natural logarithms of both sides of the equation and use ②、③ln (e5-3x)=ln10∴5-3x=ln10x=(5-ln10)/3Example 9 Express ln a+(ln b)/2 as a single logarithm.Solution Using laws of logarithms we have:ln a+(ln b)/2=ln a+ln b1/2=ln(ab1/2)1.6.5 ☆Change of Base formula For any positive number a (a≠1), we havel og a x=ln x/ ln a1.6.6 Inverse trigonometric functions⑴Inverse sine function or Arcsine functionsin-1x=y sin y=x and -π/2≤y≤π / 2,-1≤x≤1 See Fig.18、20 P72Example13 ① sin-1 (1/2) or arcsin(1/2) ② tan(arcsin1/3)Solution①∵sin (π/6)=1/2,π/6 lies between -π/2 and π / 2,∴sin-1 (1/2)=π/6② Let θ=arcsin1/3,so sinθ=1/3tan(arcsin1/3)=tanθ= s inθ/cosθ= (1/3)/(1-s in2θ)1/2=1/(8)1/2Usefully equations:①sin-1(sin x)=x for -π/2≤x≤π / 2②sin (sin-1x)=x for -1≤x≤1⑵Inverse cosine function or Arccosine functioncos-1x=y cos y=x and 0 ≤y≤π,-1≤x≤1 See Fig.21、22 P73Usefully equations:①cos-1(cos x)=x for 0 ≤x≤π②cos (cos-1x)=x for -1≤x≤1⑶Inverse Tangent function or Arctangent functiontan-1x=y tan y=x and -π/2<y<π / 2 ,x∈R See Fig.23 P73、Fig.25 P74Example 14 Simplify the expression cos(ta n-1x).Solution 1 Let y=tan-1 x,Then tan y=x and -π/2<y<π / 2 ,We want find cos y but since tan y is known, it is easier to find sec y first:sec2y=1 +tan2y sec y=(1 +x2 )1/2∴cos(ta n-1x)=cos y =1/ sec y=(1 +x2)-1/2Solution 2∵cos(ta n-1x)=cos y∴cos(ta n-1x)=(1 +x2)-1/2⑷Other Inverse trigonometric functionscsc-1x=y∣x∣≥1csc y=x and y∈(0,π / 2]∪(π,3π / 2]sec-1x=y∣x∣≥1sec y=x and y∈[0,π / 2)∪[π,3π / 2]cot-1x=y x∈R cot y=x and y∈(0,π)Exercises P 74-85Key words and PhrasesCalculus 微积分学Set 集合Variable 变量Domain 定义域Range 值域Arbitrary number 独立变量Independent variable 自变量Dependent variable 因变量Square root 平方根Curve 曲线Interval 区间Interval notation 区间符号Closed interval 闭区间Opened interval 开区间Absolute 绝对值Absolute value 绝对值Symmetry 对称性Represent of a function 函数的表述(描述)Even function 偶函数Odd function 奇函数Increasing Function 增函数Increasing Function 减函数Empirical model 经验模型Essential Function 基本函数Linear function 线性函数Polynomial function 多项式函数Coefficient 系数Degree 阶Quadratic function 二次函数(方程)Cubic function 三次函数(方程)Power functions 幂函数Reciprocal function 反比函数Rational function 有理函数Algebra 代数Algebraic function 代数函数Integer 整数Root function 根式函数(方程)Trigonometric function 三角函数Exponential function 指数函数Inverse function 反函数Logarithm function 对数函数Inverse trigonometric function 反三角函数Natural logarithm function 自然对数函数Chang of base of formula 换底公式Transcendental function 超越函数Transformations of functions 函数的变换Vertical shifts 垂直平移Horizontal shifts 水平平移Stretch 伸张Reflect 反演Combinations of functions 函数的组合Composition of functions 函数的复合Composition function 复合函数Intersection 交集Quotient 商Arithmetic 算数。

Corresponding to this we define a function cosp,q by the prescription d cosp,q (x ) = sinp,q (x ), x ∈ R. (3) dx Clearly cosp,q is even, 2πp,q -periodic and odd about πp,q ; and cos2,2 = cos. If x ∈ [0, πp,q /2], then from the definition it follows that cosp,q (x ) = (1 − (sinp,q (x ))q )1/p . (4) Moreover, the asymmetry and periodicity show that | sinp,q (x )|q + | cosp,q (x )|p = 1, We will use: πp := πp,p , sinp := sinp,p and cosp := cosp,p . x ∈ R. (5)
