derivative of

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

- sin (2 x)

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

2 cos (x) (- sin (x)) : - sin (2 x)

= - sin (2 x)

\frac{d}{d x} (\frac{( d ^{2} y ( d , x ) )}{( d x ^{2} )})

\int (sec (θ)) d θ

\frac{d}{d x} y = csc^{2} (x)

\frac{1}{( x ^{- 2} )}

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