derivative of sin^2(2x^3+3x)

Solution

\frac{d}{d x} (sin^{2} (2 x^{3} + 3 x))

Solution

sin (2 (2 x^{3} + 3 x)) (3 + 6 x^{2})

Solution steps

\frac{d}{d x} (sin^{2} (2 x^{3} + 3 x))

Apply the chain rule:

2 sin (2 x^{3} + 3 x) \frac{d}{d x} (sin (2 x^{3} + 3 x))

= 2 sin (2 x^{3} + 3 x) \frac{d}{d x} (sin (2 x^{3} + 3 x))

\frac{d}{d x} (sin (2 x^{3} + 3 x)) = cos (2 x^{3} + 3 x) (6 x^{2} + 3)

= 2 sin (2 x^{3} + 3 x) cos (2 x^{3} + 3 x) (6 x^{2} + 3)

Use the Double Angle identity:

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

= sin (2 (2 x^{3} + 3 x)) (3 + 6 x^{2})
