derivative of

f (x) = - 2 cos (x)

2 sin (x)

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

= - 2 (- sin (x))

Simplify

= 2 sin (x)

\int x - \frac{2}{x} d x

y^{^{''}} + 25 y = sin (5 t)

x \to 16 lim (x^{2} - 9)

\int \frac{2 x}{( x ^{2} + 1 ) ^{3}} d x

\int tan^{5} (1) d x
