integral of e^x*sin^2(x)

\int e^{x} \cdot sin^{2} (x) d x

e^{x} sin^{2} (x) + \frac{2}{5} e^{x} cos (2 x) - \frac{1}{5} e^{x} sin (2 x) + C

Solution steps

\int e^{x} sin^{2} (x) d x

Apply Integration By Parts

: sin^{2} (x) e^{x} - \int sin (2 x) e^{x} d x

= sin^{2} (x) e^{x} - \int sin (2 x) e^{x} d x

\int sin (2 x) e^{x} d x = - \frac{2 e ^{x} cos ( 2 x )}{5} + \frac{e ^{x} sin ( 2 x )}{5}

= sin^{2} (x) e^{x} - (- \frac{2 e ^{x} cos ( 2 x )}{5} + \frac{e ^{x} sin ( 2 x )}{5})

Simplify

sin^{2} (x) e^{x} - (- \frac{2 e ^{x} cos ( 2 x )}{5} + \frac{e ^{x} sin ( 2 x )}{5}) : e^{x} sin^{2} (x) + \frac{2}{5} e^{x} cos (2 x) - \frac{1}{5} e^{x} sin (2 x)

= e^{x} sin^{2} (x) + \frac{2}{5} e^{x} cos (2 x) - \frac{1}{5} e^{x} sin (2 x)

Add a constant to the solution

= e^{x} sin^{2} (x) + \frac{2}{5} e^{x} cos (2 x) - \frac{1}{5} e^{x} sin (2 x) + C

\int 4 x^{- 2} ln (- x) d x

5 sin (x)

\int 8 x^{- \frac{2}{3}} d x

\int \frac{x ^{4}}{25 + 4 x ^{2}} d x

\int x e^{x} ln (x) d x
