\frac{d}{d x} (cot (7 x))

- csc^{2} (7 x) \cdot 7

Solution steps

\frac{d}{d x} (cot (7 x))

Apply the chain rule:

- csc^{2} (7 x) \frac{d}{d x} (7 x)

= - csc^{2} (7 x) \frac{d}{d x} (7 x)

\frac{d}{d x} (7 x) = 7

= - csc^{2} (7 x) \cdot 7

\int \frac{1}{x ^{2}} - \frac{1}{x ^{3}} d x

\frac{d}{d u} (x^{2} + x y (x, u) (x, u)^{3})

\int t ln (t) d t

\int x^{\frac{5}{4}} d x

t^{2} \frac{d ^{2} y}{d t ^{2}} + 2 t \frac{d y}{d t} - 6 y = 0
