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

- 2 sin (2 t)

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 2 \frac{d}{d t} (cos^{2} (t))

Apply the chain rule:

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

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

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

= 2 \cdot 2 cos (t) (- sin (t))

Simplify

2 \cdot 2 cos (t) (- sin (t)) : - 2 sin (2 t)

= - 2 sin (2 t)

\int x (3 x^{2} - 5)^{10} d x

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

f (x) = \frac{3}{x + 5}

\int (- 2 e^{x} - \frac{6}{x}) d x

y = \frac{3}{x ^{6}} + \frac{1}{x ^{5}} - \frac{7}{x ^{2}}
