# {eq}f(x)=\log_{10}(1+\cos x) {/eq} Find {eq}f'(x) {/eq}

## Question:

{eq}f(x)=\log_{10}(1+\cos x) {/eq} Find {eq}f'(x) {/eq}

## First Order Derivative of the Function:

To find the first order derivative of any function, we differentiate the given function once by using the standard rule and formula for differentiation. The second order derivative means the function has to be differentiated twice.
