integral of e^{3x}sin(5x)

\int e^{3 x} sin (5 x) d x

- \frac{5 e ^{3 x} cos ( 5 x )}{34} + \frac{3 e ^{3 x} sin ( 5 x )}{34} + C

Solution steps

\int e^{3 x} sin (5 x) d x

Apply Integration By Parts

: - \frac{1}{5} e^{3 x} cos (5 x) - \int - \frac{3}{5} e^{3 x} cos (5 x) d x

= - \frac{1}{5} e^{3 x} cos (5 x) - \int - \frac{3}{5} e^{3 x} cos (5 x) d x

Take the constant out:

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

= - \frac{1}{5} e^{3 x} cos (5 x) - (- \frac{3}{5} \cdot \int e^{3 x} cos (5 x) d x)

Apply Integration By Parts

: \frac{1}{5} e^{3 x} sin (5 x) - \int \frac{3}{5} e^{3 x} sin (5 x) d x

= - \frac{1}{5} e^{3 x} cos (5 x) - (- \frac{3}{5} (\frac{1}{5} e^{3 x} sin (5 x) - \int \frac{3}{5} e^{3 x} sin (5 x) d x))

Take the constant out:

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

= - \frac{1}{5} e^{3 x} cos (5 x) - (- \frac{3}{5} (\frac{1}{5} e^{3 x} sin (5 x) - \frac{3}{5} \cdot \int e^{3 x} sin (5 x) d x))

Therefore

\int e^{3 x} sin (5 x) d x = - \frac{1}{5} e^{3 x} cos (5 x) - (- \frac{3}{5} (\frac{1}{5} e^{3 x} sin (5 x) - \frac{3}{5} \cdot \int e^{3 x} sin (5 x) d x))

Isolate

\int e^{3 x} sin (5 x) d x

= - \frac{5 e ^{3 x} cos ( 5 x )}{34} + \frac{3 e ^{3 x} sin ( 5 x )}{34}

Add a constant to the solution

= - \frac{5 e ^{3 x} cos ( 5 x )}{34} + \frac{3 e ^{3 x} sin ( 5 x )}{34} + C

t^{3} e^{t} t

n \to \infty lim (c^{n})

y = \frac{4 ln ( 3 x )}{4 - 5 x}

y^{^{''}} + y^{^{'}} - 2 y = 0, y (0) = 1, y^{^{'}} (0) = 1
