\frac{d}{d x} (20 cos (x))

- 20 sin (x)

Solution steps

\frac{d}{d x} (20 cos (x))

Take the constant out:

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

= 20 \frac{d}{d x} (cos (x))

Apply the common derivative:

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

= 20 (- sin (x))

Simplify

= - 20 sin (x)

\frac{\partial}{\partial x} (5 x^{2} + y^{2})

\int 4 x ln (7 x) d x

\frac{d v}{d t} = 9.8 - 0.6

\int_{1}^{4} 2 π x (- \frac{3}{2} x + 6) d x

d er i v a t i v e f (x) = x^{3} (2 x - 1)
