integral of e^{6x}sin(4x)

\int e^{6 x} sin (4 x) d x

- \frac{e ^{6 x} cos ( 4 x )}{13} + \frac{3 e ^{6 x} sin ( 4 x )}{26} + C

Solution steps

\int e^{6 x} sin (4 x) d x

Apply Integration By Parts

: - \frac{1}{4} e^{6 x} cos (4 x) - \int - \frac{3}{2} e^{6 x} cos (4 x) d x

= - \frac{1}{4} e^{6 x} cos (4 x) - \int - \frac{3}{2} e^{6 x} cos (4 x) d x

Take the constant out:

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

= - \frac{1}{4} e^{6 x} cos (4 x) - (- \frac{3}{2} \cdot \int e^{6 x} cos (4 x) d x)

Apply Integration By Parts

: \frac{1}{4} e^{6 x} sin (4 x) - \int \frac{3}{2} e^{6 x} sin (4 x) d x

= - \frac{1}{4} e^{6 x} cos (4 x) - (- \frac{3}{2} (\frac{1}{4} e^{6 x} sin (4 x) - \int \frac{3}{2} e^{6 x} sin (4 x) d x))

Take the constant out:

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

= - \frac{1}{4} e^{6 x} cos (4 x) - (- \frac{3}{2} (\frac{1}{4} e^{6 x} sin (4 x) - \frac{3}{2} \cdot \int e^{6 x} sin (4 x) d x))

Therefore

\int e^{6 x} sin (4 x) d x = - \frac{1}{4} e^{6 x} cos (4 x) - (- \frac{3}{2} (\frac{1}{4} e^{6 x} sin (4 x) - \frac{3}{2} \cdot \int e^{6 x} sin (4 x) d x))

Isolate

\int e^{6 x} sin (4 x) d x

= - \frac{e ^{6 x} cos ( 4 x )}{13} + \frac{3 e ^{6 x} sin ( 4 x )}{26}

Add a constant to the solution

= - \frac{e ^{6 x} cos ( 4 x )}{13} + \frac{3 e ^{6 x} sin ( 4 x )}{26} + C

x \to \infty lim (- x ln (x))

x \to 11 lim (\frac{x - 11}{1 1 ^{2} - 121})

\frac{( 3 s + 16 )}{s ^{2} - 16}

x \to 2 lim (3 ∣ x - 2 ∣)

x \to 7 lim (\frac{x ^{2} + 7}{x})
