integral of sin(2x)e^x

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

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

Solution steps

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

Apply Integration By Parts

= - \frac{1}{2} e^{x} cos (2 x) - \int - \frac{1}{2} e^{x} cos (2 x) d x

Take the constant out:

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

= - \frac{1}{2} e^{x} cos (2 x) - (- \frac{1}{2} \cdot \int e^{x} cos (2 x) d x)

Apply Integration By Parts

= - \frac{1}{2} e^{x} cos (2 x) - (- \frac{1}{2} (e^{x} \frac{1}{2} sin (2 x) - \int e^{x} \frac{1}{2} sin (2 x) d x))

Take the constant out:

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

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

Therefore

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

Isolate

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

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

Add a constant to the solution

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

d er i v a t i v e p (x) = x^{4} - 3 x^{3} + 10 x^{2} - 6 x - 20

\int \frac{1}{( 3 - x ) ^{2}} d x

\int - e^{- 2 t} d t

x \to 1 lim (x^{2} - 2)

t a y l or e^{2 x}, 3
