1.If you see a rational function with an x value on the numerator as well as on the denominator, a mental check should go off in your head: USE THE QUOTIENT RULE!
*When Do We Use The Quotient Rule?!*
This is probably the most obvious clue that can lead you to use the quotient rule. 2.You use the quotient rule to find the derivative of a rational expression. 3.WARNING! Although the quotient rule is effective in its use, it can be very lengthy. We suggest that you make sure the problem you are solving for has an x value on both the numerator and denominator, if only a number is present on the denominator, you can discard using the quotient rule and move on to use the power rule. * It could save you from too much mental exhaustion* : )

不连续的函数一定不可导。

.函数的可导性与导函数一般地,假设一元函数y=f(x )在点x0的某个邻域N(x0,δ)内有定义,当自变量取的增量Δx=x-x0时,函数相应增量为△y=f(x0+△x)-f(x0),若函数增量△y与自变量增量△x之比当△x→0时的极限存在且有限,就说函数f(x)在x0点可导,并将这个极限称之为f在x0点的导数或变化率。
“点动成线”:若函数f在区间I 的每一点都可导,便得到一个以I为定义域的新函数,记作f(x)' 或y',称之为f的导函数,简称为导数.导数的几何意义函数y=f(x)在x。

导数英文版知识点总结
导数英文版知识点总结IntroductionThe concept of derivatives is a fundamental concept in calculus and mathematics. It is a powerful tool used to analyze the behavior of functions, solve problems in various fields such as physics, engineering, and economics, and has wide applications in real-life situations. In this article, we will summarize the key knowledge points of derivatives, including the definition of derivatives, the rules for finding derivatives, applications of derivatives, and some important theorems related to derivatives.Definition of DerivativesThe derivative of a function at a point is defined as the limit of the average rate of change of the function over a small interval around the point, as the interval becomes infinitesimally small. Mathematically, the derivative of a function f(x) at a point x=a, denoted by f'(a) ordf/dx|a, is defined as:\[ f'(a) = \lim _{h \to 0} \frac{f(a + h) - f(a)}{h} \]The derivative measures the rate at which the function changes at a specific point, or the slope of the tangent line to the function at that point.Rules for Finding DerivativesThere are several rules and formulas for finding derivatives of different types of functions. The basic rules for finding derivatives are as follows:1. Power Rule: The derivative of a power function f(x) = x^n, where n is a constant, is given by f'(x) = nx^(n-1).2. Constant Rule: The derivative of a constant function f(x) = c, where c is a constant, is zero.3. Sum and Difference Rule: The derivative of the sum or difference of two functions is the sum or difference of their derivatives.4. Product Rule: The derivative of the product of two functions u(x) and v(x) is given by (uv)' = u'v + uv'.5. Quotient Rule: The derivative of the quotient of two functions u(x) and v(x) is given by (u/v)' = (u'v - uv')/v^2.6. Chain Rule: If y = f(g(x)), then the derivative of y with respect to x is given by dy/dx =f'(g(x))g'(x).These rules are fundamental for finding derivatives of algebraic, trigonometric, exponential, and logarithmic functions.Applications of DerivativesDerivatives have wide applications in various fields, including physics, engineering, economics, and biology. Some common applications of derivatives are:1. Optimization Problems: Derivatives are used to find the maximum or minimum values ofa function, such as the maximum profit, minimum cost, maximum area, or minimum distance.2. Rate of Change: Derivatives are used to measure the rate of change of a quantity over time, such as the velocity of an object, the growth of a population, or the rate of decay of a radioactive substance.3. Tangent Lines and Linear Approximations: Derivatives are used to find the equation of the tangent line to a curve at a specific point, and to approximate the value of a function near that point.4. Related Rates: Derivatives are used to solve problems involving the rates of change of two or more related quantities, such as the changing area of a rectangle, the changing volume ofa cone, or the changing distance between two moving objects.5. Newton's Laws of Motion: Derivatives are used to describe the motion of objects in terms of position, velocity, and acceleration, and to analyze the forces acting on the objects. Important Theorems Related to DerivativesThere are several important theorems related to derivatives that are widely used in calculus and mathematical analysis. Some of the key theorems are:1. Mean Value Theorem: If a function f(x) is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one point c in (a, b) such that f'(c) = (f(b) - f(a))/(b - a).2. Rolle's Theorem: If a function f(x) is continuous on the closed interval [a, b], differentiable on the open interval (a, b), and f(a) = f(b), then there exists at least one point c in (a, b) such that f'(c) = 0.3. Cauchy's Mean Value Theorem: If two functions u(x) and v(x) are continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one point c in (a, b) such that (u(b) - u(a))v'(c) = (v(b) - v(a))u'(c).4. Fermat's Theorem: If a function f(x) has a local maximum or minimum at a point c, andf'(c) exists, then f'(c) = 0.5. L'Hôpital's Rule: If the limit of a quotient of two functions is of the form 0/0 or ∞/∞, then the limit of the quotient of their derivatives is equal to the limit of the original quotient, provided the limit of the derivative exists.ConclusionThe concept of derivatives is a fundamental concept in calculus, and it plays a crucial role in analyzing the behavior of functions, solving problems in various fields, and making predictions about real-life situations. This article has summarized the key knowledge points of derivatives, including the definition of derivatives, the rules for finding derivatives, applications of derivatives, and important theorems related to derivatives. A thorough understanding of these knowledge points is essential for mastering the techniques of finding derivatives and applying them to solve real-world problems.。

Math3B Worksheet1G.Kennedy1Derivative FormulasThe following two properties are known as the linearity of the deriva-tive:ddx(f(x)+g(x))=f (x)+g (x)“The derivative of the sum is the sum of the derivatives.”or“You can take the derivative term by term.”ddx[cf(x)]=cf (x)“You can pull out constants.”Other Rules:•Power Rule:ddx (x n)=nx n−1What does this say about the derivative of a constant?•Product Rule:ddx[f(x)g(x)]=f(x)g (x)+g(x)f (x)•Quotient Rule:ddx [f(x)g(x)]=g(x)f (x)−f(x)g (x)[g(x)]2“LodiHi-HidiLo all over LoLo.”•Chain Rule:ddxf(g(x))=f (g(x))g (x)•ddx(e x)=e x•ddx ln(|x|)=1xd dx (sin(x))=cos(x)ddx(cos(x))=−sin(x)ddx(tan(x))=sec2(x)d dx (csc(x))=−csc(x)cot(x)ddx(sec(x))=sec(x)tan(x)ddx(cot(x))=−csc2(x)ddx(sin−1(x))=1√1−x2ddx(cos−1(x)=−1√1−x2ddx(tan−1(x))=11+x2You will need to memorize these!You spent the entire last coursemastering how to calculate a derivative,and this course will be all about undoing your hard work.:(So you still have to have all of these memorized.12The AntiderivativeThe antiderivative of a function f(x)is a function F(x)whose derivative is f(x).Examples:If f (x)=2x2,then f(x)=If f (x)=x3,then f(x)=If f(x)=sin(x),then F(x)=Question:Are antiderivatives unique?•Power Rule:If f (x)=x n,then what is f(x)?In other words,(n=−1)x n dx=•If f(x)=1x,what is F(x)?In other words,dxx=•If f(x)=e x,what is F(x)?In other words,e x dx=•If f (x)=e x+6x,what is f(x)?Fill out the following antiderivative formulas if possible:sin(x)dx=cos(x)dx=sec2(x)dx=tan(x)dx=ln(x)dx=etc...Everything on thefirst page gives you an integration formula.But some seemingly common functions don’t have an obvious derivative while some seemingly obscure functions do!2。
Formulaandproofofderivative(导数的公式及证明)
Formula and proof of derivative(导数的公式及证明)The derivative formula and the proof here will enumerate the derivatives of five basic elementary functions and their derivation process (elementary function can be calculated by it): basic derivative formula1. constant function (i.e. constant) y=c (C constant) y'=02. power function y=x^n, y'=nx^ (n-1) (n, Q*) 1/X3. index function by derivative (1) y=a^x, y'=a^xlna (2) by y=e^x y'=e^x; only a guide function for itself function logarithmic function (1) y=logaX4. y'=1 (a>0, /xlna and a is not equal to 1, x>0) by y=lnx, y'=1/x5.; sine function y= (SiNx) y'=cosx y= (cosx)6. cosine function y'=-sinx7. (TaNx) y'=1/ tangent function y= (cosx) ^28. (Cotx) y'=-1/ cotangent function y= (SiNx) ^29. y= (inverse sine function arcsinx y'=1/ 1-x^2 10.) V arccosine function y= (arccosx) y'=-1/ 1-x^2 11. V arctan function y= (arctanx) y'=1/ (1+x^2) 12. - y= (arccotx) y'=-1/ cotangent function (1+x^2) in order to facilitate memory, are sorted out the following formula: often zero power down time, 对导数(e 为底时直接导数,a为底时乘以lna),指不变(特别的,自然对数的指数函数完全不变,一般的指数函数须乘以lna);正变余,余变正,切割方(切函数是相应割函数(切函数的倒数)的平方),割乘切,反分式在推导的过程中有这几个常见的公式需要用到:1.y=f[g(x)],y'=f'[g(x)]·g'(x)‘f'[g(x)]中g(x)看作整个变量,而g'(x)中把x看作变量’ 2.y=u/v,y'=(u'v-uv')/v^2 3.原函数与反函数导数关系(由三角函数导数推反三角函数的):y=f(x)的反函数是x=g(y),则有y'=1/x' 证:1.显而易见,y=c是一条平行于x轴的直线,所以处处的切线都是平行于x的,故斜率为0。
