This integral is easily solved by using the Integration by Parts formula. Follow the steps below to solve:
| Reciting the Integration by Parts equation: |  | |
| Set u=x and dv=sin(x) dx and solve for du and v: |  |  |
 |  | |
| Plugging in u, du, v and dv into the IBP equation above: |  | |
| Simplify and then integrate the remaining integral we arrive at our final answer: |  | |
The final answer is -xcos(c)+sin(x)+C:
