Evaluate the integral. $($Remember the constant of integration.$)$

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}{e}^{8}sin(9)d$

$e^8(\frac{8sin9-9cos9}{145})+C$

Check your answer by taking the derivative.

Please try again. Recall that ${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}$udv$=uv-{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}$vdu.

Try using integration by parts twice, thus repeating the same integral. Once you've repeated the integral, move both instances of it to one side of the equation and solve for it$.$
