WebThe derivative of a function represents its a rate of change (or the slope at a point on the graph). What is the derivative of zero? The derivative of a constant is equal to zero, … WebDec 20, 2024 · Example \(\PageIndex{2}\):Using Properties of Logarithms in a Derivative. Find the derivative of \(f(x)=\ln (\frac{x^2\sin x}{2x+1})\). Solution. At first glance, taking this derivative appears rather complicated. However, by using the properties of logarithms prior to finding the derivative, we can make the problem much simpler.

WebNov 10, 2024 · Note that ln x is defined only for x > 0. It is sometimes useful to consider the function ln x , a function defined for x ≠ 0. When x < 0, ln x = ln ( − x) and (3.6.4) d d x ln x = d d x ln ( − x) = 1 − x ( − 1) = 1 x. Thus whether x is positive or negative, the derivative is the same. What about the functions a x and log a x? WebThe derivative of a constant is 0, so the derivative of 0 is 0.
