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

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

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

Solution steps

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

Apply Integration By Parts

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

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

Take the constant out:

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

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

Apply Integration By Parts

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

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

Take the constant out:

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

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

Therefore

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

Isolate

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

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

Add a constant to the solution

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

x^{3} + y^{3} = 6 x y, (3, 3)

x - x^{3}

\int \frac{3 e ^{2 x}}{e ^{2 x} + 15 e ^{x} + 54} d x

f (x) = \frac{4}{x ^{2}}

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