derivative of

cos^{2} (5 x)

- 5 sin (10 x)

Solution steps

\frac{d}{d x} (cos^{2} (5 x))

Apply the chain rule:

2 cos (5 x) \frac{d}{d x} (cos (5 x))

= 2 cos (5 x) \frac{d}{d x} (cos (5 x))

\frac{d}{d x} (cos (5 x)) = - sin (5 x) \cdot 5

= 2 cos (5 x) (- sin (5 x) \cdot 5)

Simplify

2 cos (5 x) (- sin (5 x) \cdot 5) : - 5 sin (10 x)

= - 5 sin (10 x)

\frac{1 - t ^{2}}{4}

\frac{d}{d s} (\frac{( 13 ( s + 2 ) ( s + 5 ) )}{( s ( s + 3 ) )})

q (t) = 6 t^{2} + 5 t + 4

\frac{5}{( 1 + 3 x )}

\frac{d}{d t} (- 38 t + 220)
