derivative of sin^3(4x^2-1)

Solution

\frac{d}{d x} (sin^{3} (4 x^{2} - 1))

Solution

24 x sin^{2} (4 x^{2} - 1) cos (4 x^{2} - 1)

Solution steps

\frac{d}{d x} (sin^{3} (4 x^{2} - 1))

Apply the chain rule:

3 (sin (4 x^{2} - 1))^{2} \frac{d}{d x} (sin (4 x^{2} - 1))

= 3 (sin (4 x^{2} - 1))^{2} \frac{d}{d x} (sin (4 x^{2} - 1))

\frac{d}{d x} (sin (4 x^{2} - 1)) = cos (4 x^{2} - 1) \cdot 8 x

= 3 (sin (4 x^{2} - 1))^{2} cos (4 x^{2} - 1) \cdot 8 x

Simplify

= 24 x sin^{2} (4 x^{2} - 1) cos (4 x^{2} - 1)
