f(x) where f'(x) exists. D. The derivative of the function f(x) is a function, usually denoted f'(x), whose output f'(a) is the instantaneous rate of change of f(x) at the point (a, f((a)), where a is any value of x in the domain for f(x) where f'(x) exists....
The rate of change of a function at a certain point is called ___. A. integral B. derivative C. limit D. continuity 相关知识点: 试题来源: 解析 B。本题考查微积分基本概念。“derivative”是导数的意思,函数在某一点的变化率就是导数。“integral”是积分;“limit”是极限;“continuity”是连续...
The instantaneous rate of change of any function (commonly called rate of change) can be found in the same way we find velocity. The function that gives this instantaneous rate of change of a function f is called the derivative of f.Is...
The derivative in calculus is the rate of change of a function. In this lesson, explore this definition in greater depth and learn how to write derivatives. Related to this Question Given f(x)=\frac{6}{x}, using the definition of derivative, what is f'(x)?
The rate of change of temperature, T'(t)>0, is increasing when T''(t)\ >\ 0. Use the Derivative function on your calculator to compute T''(7), which is the derivative of T'; the result is T''(7)=-0.301<0 ⇒ T'(t) is decreasing, i.e., the rate of change of the ...
What is the definition of the derivative? Example: An acquisition officer observed the cost of similar defense contracts for the past 10 years. He is interested in the rate of change in the costs for contracts that last 2 years. The following table depicts the values he obtained. Duration ...
aFormula (2.9) expresses the rate of change of φ per unit volume plus the net flow of φout of the fluid element per unit volume. It is now re-written to illustrate its relationship with the substantive derivative of φ: 惯例(2.9)表达φ的变动的率每个单位体积加上可变的元素的φout净流程...
