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