Question

Find the derivative of the following functions (it is to be understood that a, b, c, d, p, q, r and s are fixed non-zero constants and m and n are integers):
$sin(x+a)$

Answer 1

Here $f\left(x\right)=sin(x+a)$

$\therefore f^{\prime }\left(x\right)=\frac{d}{dx}\left[sin\right(x+a\left)\right]$

$=cos(x+a).\frac{d}{dx}(x+a)=cos(x+a)$
