\frac{d}{d x} (sin^{2} (π x))

π sin (2 π x)

Solution steps

\frac{d}{d x} (sin^{2} (π x))

Apply the chain rule:

2 sin (π x) \frac{d}{d x} (sin (π x))

= 2 sin (π x) \frac{d}{d x} (sin (π x))

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

= 2 sin (π x) cos (π x) π

Use the Double Angle identity:

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

= π sin (2 π x)
