\frac{d}{d x} (cot (9 x))

- csc^{2} (9 x) \cdot 9

Solution steps

\frac{d}{d x} (cot (9 x))

Apply the chain rule:

- csc^{2} (9 x) \frac{d}{d x} (9 x)

= - csc^{2} (9 x) \frac{d}{d x} (9 x)

\frac{d}{d x} (9 x) = 9

= - csc^{2} (9 x) \cdot 9

f (x) = - 9 cos (3 x)

\frac{d y}{d x}, ln (x^{2} + y^{2}) = 2 (arctan (\frac{y}{x}))
