Differentiate the following functions with respect to x: ( ) - Vidyadip

Question

Differentiate the following functions with respect to x:
$\sin(\log\text{x})$

✓

Answer

Consider $\text{y}=\sin(\log\text{x})$
Differentiate it with respect to x,
$\frac{\text{dy}}{\text{dx}}=\frac{\text{d}}{\text{dx}}\sin(\log\text{x})$
$=\cos(\log\text{x})\frac{\text{d}}{\text{dx}}(\log\text{x})$
[Using chain rule]
$=\frac{1}{\text{x}}\cos(\log\text{x})$
Hence, the solution is $\frac{\text{d}}{\text{dx}}=(\sin(\log\text{x}))=\frac{1}{\text{x}}\cos(\log\text{x})$
