This is a menu driven program which finds areas under curves using different techniques of numerical integration.

Enter the function into y_{1}

The techniques you can use are:

- Left-hand endpoints
- Right-hand endpoints
- Mid-points
- Simpson's Rule
- Trapezoid Rule

I found out that the routines didn't actually include the mid-point formula.
It does now. I also modified some of the code so it should appear to run
faster.
