英语数学专用词汇表
英语数学专用词汇表In order to provide a comprehensive list of English mathematical terminology, I will present various mathematical concepts and terms across different branches of mathematics. Please note that this list is by no means exhaustive, but it should serve as a useful reference.1. Arithmetic- Addition: The process of combining two or more numbers to find their sum.- Subtraction: The process of finding the difference between two numbers.- Multiplication: The process of combining repeated addition of the same number or group of numbers.- Division: The process of separating a number into equal parts or groups.2. Algebra- Variable: A symbol used to represent an unknown quantity or value.- Equation: A mathematical statement that two expressions are equal.- Inequality: A mathematical statement that denotes a relationship between two expressions that may or may not be equal.- Polynomial: An algebraic expression consisting of variables, coefficients, and exponents.- Quadratic function: A function that can be written in the form of ax^2 + bx + c, where a, b, and c are constants.3. Geometry- Point: A location in space with no size or dimension.- Line: A straight path with infinite length and no width.- Angle: The union of two rays with a common endpoint.- Triangle: A polygon with three sides and three angles.- Circle: A set of all points equidistant from a fixed point called the center.4. Trigonometry- Sine: The ratio of the length of the side opposite an angle to the length of the hypotenuse in a right-angled triangle.- Cosine: The ratio of the length of the adjacent side to the length of the hypotenuse in a right-angled triangle.- Tangent: The ratio of the length of the side opposite an angle to the length of the adjacent side in a right-angled triangle.- Hypotenuse: The side opposite the right angle in a right-angled triangle.5. Calculus- Derivative: The rate at which a function changes at a particular point.- Integral: The process of calculating the total area under a curve or the accumulated change of a function from one point to another.- Limit: The value that a function approaches as the input approaches a certain value or infinity.- Differentiation: The process of finding derivatives of functions. - Integration: The process of finding integrals of functions.6. Statistics and Probability- Mean: The average value of a set of numbers.- Median: The middle value in a set of ordered numbers.- Mode: The value that appears most frequently in a set of numbers. - Probability: The likelihood or chance of an event occurring.- Standard deviation: A measure of the spread of data or how far data points deviate from the mean.It is important to note that the examples provided here barely scratch the surface of mathematical terminology. Mathematics is a vast subject with numerous branches and subfields, each with its own set of specialized vocabulary. To deepen your understanding of mathematical terminology, I recommend referring to textbooks or online resources dedicated to specific areas of mathematics.。
