derivative of

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)

2 sin (x) y^{^{'}} + y cos (x) = y^{2} cos (x)

\frac{\partial}{\partial s} (r sin (t) sin (s))

\frac{\partial}{\partial x} (\frac{4 x - y}{4 x + y})

\frac{d y}{d x} = y^{- 1} x^{- 3}

y^{^{'}} = \frac{6 y ^{2}}{x ^{2}}, y (- 2) = 5
