derivative of

7 cos (x)

- 7 sin (x)

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

= 7 (- sin (x))

Simplify

= - 7 sin (x)

\int_{- \infty}^{0} x e^{- 8 x} d x

(1 + 2 x)^{2}

y = \frac{7 x}{e ^{x}}

arctan (x - 1 + x^{2})

\int sin^{2} (4 x) \cdot cos^{2} (4 x) d x
