Derivatives of Exponential and Logarithm Functions – In this section we derive the formulas for the derivatives of the exponential and logarithm functions. Derivatives of Inverse Trig Functions ...
When we credit Newton and Leibniz with developing calculus, we are really referring to the fact that Newton and Leibniz were the first to understand the relationship between the derivative and the integral. Both mathematicians benefited from the work of predecessors, such as Barrow, Fermat, and Cavalieri. The initial relationship between the ...

Sep 7, 2022 · Definition: Derivative. Let f(x) be a function defined in an open interval containing a. The derivative of the function f(x) at a, denoted by f′ (a), is defined by. f′ (a) = lim x → a f(x) − f(a) x − a. provided this limit exists. Alternatively, we may also define the derivative of f(x) at a as.
If x ≠ a is in I, then. Q = f ( x) − f ( a) x − a. is a difference quotient. Also, if h ≠ 0 is chosen so that a + h is in I, then. Q = f ( a + h) − f ( a) h. is a difference quotient with increment h. View several Java applets on the development of the derivative.
As we have seen, the derivative of a function at a given point gives us the rate of change or slope of the tangent line to the function at that point. If we differentiate a position function at a given time, we obtain the velocity at that time. It seems reasonable to conclude that knowing the derivative of the function at every point would ...
Unit test. The derivative of a function describes the function's instantaneous rate of change at a certain point - it gives us the slope of the line tangent to the function's graph at that point. See how we define the derivative using limits, and learn to find derivatives quickly with the very useful power, product, and quotient rules.
3.1: Introducing the Derivative. The slope of the tangent line to a curve measures the instantaneous rate of change of a curve. We can calculate it by finding the limit of the difference quotient or the difference quotient with increment h . The derivative of a function f (x) at a value a is found using either of the definitions for the slope ...
