derivative of

ln (81 sin^{2} (x))

2 cot (x)

Solution steps

\frac{d}{d x} (ln (81 sin^{2} (x)))

Apply the chain rule:

\frac{1}{81 sin ^{2} ( x )} \frac{d}{d x} (81 sin^{2} (x))

= \frac{1}{81 sin ^{2} ( x )} \frac{d}{d x} (81 sin^{2} (x))

\frac{d}{d x} (81 sin^{2} (x)) = 162 sin (x) cos (x)

= \frac{1}{81 sin ^{2} ( x )} \cdot 162 sin (x) cos (x)

Simplify

\frac{1}{81 sin ^{2} ( x )} \cdot 162 sin (x) cos (x) : 2 cot (x)

= 2 cot (x)

\int \frac{200}{20 - 3 x} d x

x \to 1 lim (x^{3} + 1)

x \to \infty lim (5 \cdot x)

\int \frac{1}{( 1 + x ) x} d x
