integral of (sin^2(x)tan^2(x))/2

integral

\frac{sin ^{2} ( x ) tan ^{2} ( x )}{2}

\frac{1}{2} (sin^{3} (x) cos (x) - \frac{3}{2} x + \frac{3}{4} sin (2 x) + sin^{4} (x) tan (x)) + C

Solution steps

\int \frac{sin ^{2} ( x ) tan ^{2} ( x )}{2} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int sin^{2} (x) tan^{2} (x) d x

Rewrite using trig identities

= \frac{1}{2} \cdot \int \frac{sin ^{4} ( x )}{cos ^{2} ( x )} d x

Apply Integration By Parts

: - \int 4 sin^{4} (x) d x + sin^{4} (x) tan (x)

= \frac{1}{2} (- \int 4 sin^{4} (x) d x + sin^{4} (x) tan (x))

\int 4 sin^{4} (x) d x = - sin^{3} (x) cos (x) + \frac{3}{2} x - \frac{3}{4} sin (2 x)

= \frac{1}{2} (- (- sin^{3} (x) cos (x) + \frac{3}{2} x - \frac{3}{4} sin (2 x)) + sin^{4} (x) tan (x))

Simplify

= \frac{1}{2} (sin^{3} (x) cos (x) - \frac{3}{2} x + \frac{3}{4} sin (2 x) + sin^{4} (x) tan (x))

Add a constant to the solution

= \frac{1}{2} (sin^{3} (x) cos (x) - \frac{3}{2} x + \frac{3}{4} sin (2 x) + sin^{4} (x) tan (x)) + C

\frac{x}{x - 1}

\frac{1}{( 2 x )}

\frac{ln ( x )}{( 1 + 2 x ) ^{2}}

\frac{1}{( 100 - n )}

\frac{- 1}{x ^{3}}
