Question
Differentiate the following function with respect to (x):

$\text{x}^4-2\sin\text{x}+\cos\text{x}$

Answer

We have to differentiate f(x) with respect to x:

$\frac{\text{d}}{\text{dx}}(\text{x}^4-2\sin\text{x}+3\cos\text{x})$

$=\frac{\text{d}(\text{x})^4}{\text{dx}}-2\frac{\text{d}}{\text{dx}}(\sin\text{x})+\frac{\text{d}}{\text{dx}}(\cos\text{x})$

$=4\text{x}^3-2\cos\text{x}-3\sin\text{x}$
