integral of xsinh(2x)

\int x sinh (2 x) d x

\frac{1}{2} x cosh (2 x) - \frac{1}{4} sinh (2 x) + C

Solution steps

\int x sinh (2 x) d x

Apply Integration By Parts

: \frac{1}{2} x cosh (2 x) - \int \frac{1}{2} cosh (2 x) d x

= \frac{1}{2} x cosh (2 x) - \int \frac{1}{2} cosh (2 x) d x

\int \frac{1}{2} cosh (2 x) d x = \frac{1}{4} sinh (2 x)

= \frac{1}{2} x cosh (2 x) - \frac{1}{4} sinh (2 x)

Add a constant to the solution

= \frac{1}{2} x cosh (2 x) - \frac{1}{4} sinh (2 x) + C
