derivative of cos^2(3x+1-sin^2(3x+1))

Solution

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

Solution

- sin (2 (1 + 3 x)) \cdot 6

Solution steps

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

Simplify

cos^{2} (3 x + 1) - sin^{2} (3 x + 1) : cos (2 (1 + 3 x))

= \frac{d}{d x} (cos (2 (1 + 3 x)))

Apply the chain rule:

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

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

\frac{d}{d x} (2 (1 + 3 x)) = 6

= - sin (2 (1 + 3 x)) \cdot 6
