derivative of

sin^{2} (p i x)

i x sin (2 i p x)

Solution steps

\frac{d}{d p} (sin^{2} (p i x))

Treat

x

as a constant

Apply the chain rule:

2 sin (p i x) \frac{d}{d p} (sin (p i x))

= 2 sin (p i x) \frac{d}{d p} (sin (p i x))

\frac{d}{d p} (sin (p i x)) = cos (p i x) i x

= 2 sin (p i x) cos (p i x) i x

Use the Double Angle identity:

2 sin (x) cos (x) = sin (2 x)

= i x sin (2 i p x)

\int \frac{6 x ^{3} + 7 x}{( x ^{2} + 2 ) ^{2}} d x

\frac{2}{( s + 1 ) ^{3}}

\frac{d}{d x} (- 4 e^{- 2.5 x})

\int sin^{7} (x) d x

\frac{d}{d x} (ln (x + 4))
