Evaluate the following integral:

NOTE: On this page, the exponential function **f(x) = e ^{x}** is denoted by

Click the left mouse button on each of the following equations (in blue):

- Let

- Hence,
- Using the formula for integration by parts
- Now we can use integration by parts again to compute the following integral
- Let
- Hence,
- Again, using integration by parts, we get
- We can now use the above result to finish solving the problem:
