derivative of

y = sin^{2} (x) - cos^{2} (x)

2 sin (2 x)

Solution steps

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

Simplify

sin^{2} (x) - cos^{2} (x) : - cos (2 x)

= \frac{d}{d x} (- cos (2 x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - \frac{d}{d x} (cos (2 x))

Apply the chain rule:

- sin (2 x) \frac{d}{d x} (2 x)

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

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

= - (- sin (2 x) \cdot 2)

Simplify

= 2 sin (2 x)

x \to - 35 lim (34 + x)

\frac{\partial}{\partial y} (y e^{y})

\int \frac{e ^{8 x} ( e ^{- 6 x} )}{- 15 e ^{x}} d x

\frac{d}{d x} (5 x ln (7 x) - 5 x)

\int e^{5 x} sin (3 x) d x
