derivative of

f (x) = (cos (x))^{2}

- sin (2 x)

Solution steps

\frac{d}{d x} ((cos (x))^{2})

Apply the chain rule:

2 cos (x) \frac{d}{d x} (cos (x))

= 2 cos (x) \frac{d}{d x} (cos (x))

\frac{d}{d x} (cos (x)) = - sin (x)

= 2 cos (x) (- sin (x))

Simplify

2 cos (x) (- sin (x)) : - sin (2 x)

= - sin (2 x)

\int cos (n x) d x

\frac{d}{d x} (sin^{2} (3 - x))

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

6 u + 7 u

\frac{\partial}{\partial x} ((- (3 x + 9))^{9})
