derivative of

2 + 3 + cos^{2} (x)

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

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d}{d x} (2) = 0

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

= 0 - \frac{sin ( 2 x )}{2 3 + cos ^{2} ( x )}

Simplify

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

\int \frac{2}{x ^{4}} d x

\int 4 y^{3} e^{y} d y

t e^{4 t}

\frac{d}{d x} (a x sin (x) + b x cos (x))

\int e^{8 x - 7} d x
