derivative of

ln (sin (2 x))

2 cot (2 x)

Solution steps

\frac{d}{d x} (ln (sin (2 x)))

Apply the chain rule:

\frac{1}{sin ( 2 x )} \frac{d}{d x} (sin (2 x))

= \frac{1}{sin ( 2 x )} \frac{d}{d x} (sin (2 x))

\frac{d}{d x} (sin (2 x)) = cos (2 x) \cdot 2

= \frac{1}{sin ( 2 x )} cos (2 x) \cdot 2

Simplify

\frac{1}{sin ( 2 x )} cos (2 x) \cdot 2 : 2 cot (2 x)

= 2 cot (2 x)
