\frac{d}{d x} (8 + cot^{2} (x))

- \frac{csc ^{2} ( x ) cot ( x )}{8 + cot ^{2} ( x )}

Solution steps

\frac{d}{d x} (8 + cot^{2} (x))

Apply the chain rule:

\frac{1}{2 8 + cot ^{2} ( x )} \frac{d}{d x} (8 + cot^{2} (x))

= \frac{1}{2 8 + cot ^{2} ( x )} \frac{d}{d x} (8 + cot^{2} (x))

\frac{d}{d x} (8 + cot^{2} (x)) = - 2 csc^{2} (x) cot (x)

= \frac{1}{2 8 + cot ^{2} ( x )} (- 2 csc^{2} (x) cot (x))

Simplify

\frac{1}{2 8 + cot ^{2} ( x )} (- 2 csc^{2} (x) cot (x)) : - \frac{csc ^{2} ( x ) cot ( x )}{8 + cot ^{2} ( x )}

= - \frac{csc ^{2} ( x ) cot ( x )}{8 + cot ^{2} ( x )}

x \to 2 lim (3 x^{3} + x^{2} - 8)

f (x) = 6 x^{9} e^{x}

p x + d

\frac{d}{d x} (4 x ln (x) + 10)

\frac{d}{d x} (4 x^{2} - x + x)
