integral of sin(x)e^{2x}

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

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

Solution steps

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

Apply Integration By Parts

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

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

Take the constant out:

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

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

Apply Integration By Parts

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

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

Take the constant out:

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

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

Therefore

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

Isolate

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

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

Add a constant to the solution

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

f (x) = x, (25, 5)

\int (u - 2)^{3} ln (u - 2) d u

\frac{d}{d x} (\frac{x + 7}{x})

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

\frac{\partial}{\partial y} (x^{2} + yz)
