integral of e^xsin(x)x

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

x (- \frac{1}{2} e^{x} cos (x) + \frac{1}{2} e^{x} sin (x)) + \frac{1}{2} e^{x} cos (x) + C

Solution steps

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

Apply Integration By Parts

: x (- \frac{1}{2} e^{x} cos (x) + \frac{1}{2} e^{x} sin (x)) - \int \frac{1}{2} (- e^{x} cos (x) + e^{x} sin (x)) d x

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

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

= x (- \frac{1}{2} e^{x} cos (x) + \frac{1}{2} e^{x} sin (x)) - (- \frac{1}{2} e^{x} cos (x))

Simplify

= x (- \frac{1}{2} e^{x} cos (x) + \frac{1}{2} e^{x} sin (x)) + \frac{1}{2} e^{x} cos (x)

Add a constant to the solution

= x (- \frac{1}{2} e^{x} cos (x) + \frac{1}{2} e^{x} sin (x)) + \frac{1}{2} e^{x} cos (x) + C

\frac{s}{s ( s ^{2} + s + 1 )}

\int x cos^{2} (8 x) d x

\frac{d y}{d x} = \frac{x + 2}{y}

\int \frac{1}{7 x + 3} d x

\frac{d}{d t} (\frac{2 t + 7}{2 t})
