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

- sin (w x) w

Solution steps

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

Treat

w

as a constant

Apply the chain rule:

- sin (w x) \frac{d}{d x} (w x)

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

\frac{d}{d x} (w x) = w

= - sin (w x) w

\frac{d}{d t} (4 \frac{e ^{5 t}}{t ^{2} + 1})

\frac{y ^{^{''}}}{y} = - 3

\int - 25 sin (- 5 t) d t

\frac{d}{d x} (arccos (e^{6 x}))

x \to - 2 - lim (x + 2)
