What is the derivative of ln(sinhx)? Derivative:In simple language, the derivative is change in y by the change in x. Mathematically, it is denoted as dydx. As the allotted function whose derivative we have to compute is a composite function, so the rule that is used here is ...
Example 1: What is the derivative of ln(2x)? Notice that the chain rule can be used here to find the derivative. In this case, the inside function is 2x, and the outside function is ln(x). Therefore, ddxln(2x)=12x⋅ddx2x=12x⋅2=1x. It is an interesting result that ...

Find the derivative of:ln(1+5x). Question: Find the derivative of:ln(1+5x). Chain Rule: The chain rule of derivatives is used to differentiate composite functions. A composite function is a type of function that is composed of two or more sub-functions. This rule can be applied...
Derivative f’ of function f(x)=arctan x is: f’(x) = 1 / (1 + x²) for all x real. To show this result, we use derivative of the inverse function tan x.
Derivative f’ of the function f(x)=sinx is: f’(x) = cos x for any value of x. Derivative of sin x Derivative $f’$ of the function $f(x)=\sin x$ is: \(\forall x \in ]-\infty, +\infty[ , f'(x) = \cos x\) ...
