derivative of

cos (3 y)

- sin (3 y) \cdot 3

Solution steps

\frac{d}{d y} (cos (3 y))

Apply the chain rule:

- sin (3 y) \frac{d}{d y} (3 y)

= - sin (3 y) \frac{d}{d y} (3 y)

\frac{d}{d y} (3 y) = 3

= - sin (3 y) \cdot 3

\frac{d}{d x} (e^{- 5 x^{4}})

\int (x^{2} + 3) sin (x) d x

\int \frac{cos ( x )}{sin ^{4} ( x ) - 16} d x

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

d er i v a t i v e y = x (x - 14)
