derivative of

4 cos (x) + 12 x

\frac{- sin ( x ) + 3}{cos ( x ) + 3 x}

Solution steps

\frac{d}{d x} (4 cos (x) + 12 x)

Apply the chain rule:

\frac{1}{2 4 cos ( x ) + 12 x} \frac{d}{d x} (4 cos (x) + 12 x)

= \frac{1}{2 4 cos ( x ) + 12 x} \frac{d}{d x} (4 cos (x) + 12 x)

\frac{d}{d x} (4 cos (x) + 12 x) = - 4 sin (x) + 12

= \frac{1}{2 4 cos ( x ) + 12 x} (- 4 sin (x) + 12)

Simplify

\frac{1}{2 4 cos ( x ) + 12 x} (- 4 sin (x) + 12) : \frac{- sin ( x ) + 3}{cos ( x ) + 3 x}

= \frac{- sin ( x ) + 3}{cos ( x ) + 3 x}

\int_{1}^{2} \frac{5}{x ^{2}} d x

f (x) = 8 x - 3, at x = 64

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

y^{^{''}} + 11 y^{^{'}} + 22 y = 3468 e^{2 t} cos (12 t)

\int_{0}^{1} π (e^{x} + 1)^{2} d x
