integral of e^xsin(6x)

\int e^{x} sin (6 x) d x

- \frac{6 e ^{x} cos ( 6 x )}{37} + \frac{e ^{x} sin ( 6 x )}{37} + C

Solution steps

\int e^{x} sin (6 x) d x

Apply Integration By Parts

: - \frac{1}{6} e^{x} cos (6 x) - \int - \frac{1}{6} e^{x} cos (6 x) d x

= - \frac{1}{6} e^{x} cos (6 x) - \int - \frac{1}{6} e^{x} cos (6 x) d x

Take the constant out:

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

= - \frac{1}{6} e^{x} cos (6 x) - (- \frac{1}{6} \cdot \int e^{x} cos (6 x) d x)

Apply Integration By Parts

: e^{x} \frac{1}{6} sin (6 x) - \int e^{x} \frac{1}{6} sin (6 x) d x

= - \frac{1}{6} e^{x} cos (6 x) - (- \frac{1}{6} (e^{x} \frac{1}{6} sin (6 x) - \int e^{x} \frac{1}{6} sin (6 x) d x))

Take the constant out:

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

= - \frac{1}{6} e^{x} cos (6 x) - (- \frac{1}{6} (e^{x} \frac{1}{6} sin (6 x) - \frac{1}{6} \cdot \int e^{x} sin (6 x) d x))

Therefore

\int e^{x} sin (6 x) d x = - \frac{1}{6} e^{x} cos (6 x) - (- \frac{1}{6} (e^{x} \frac{1}{6} sin (6 x) - \frac{1}{6} \cdot \int e^{x} sin (6 x) d x))

Isolate

\int e^{x} sin (6 x) d x

= - \frac{6 e ^{x} cos ( 6 x )}{37} + \frac{e ^{x} sin ( 6 x )}{37}

Add a constant to the solution

= - \frac{6 e ^{x} cos ( 6 x )}{37} + \frac{e ^{x} sin ( 6 x )}{37} + C

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

\int e^{6 x} cos (2 x) d x

\frac{d}{d x} (\frac{4}{4 x})

y^{^{''}} + 2 y^{^{'}} + 1 y = 0

\frac{\partial}{\partial y} (\frac{x}{( 1 + 2 x + 3 y )})
