Purpose: This integral calculator allows the user to enter a function and immediately see the definite integral within given limts, the antiderivative with some assumed initial condition, and the area under the curve.

Restrictions on Use: None

General Information:

1. Enter your function with an independant variable of x in the bottom right text area.
2. Use two astericks to represent exponentiation (i.e. x² would be entered x**2).
3. Most mathematical functions are supported (for example. sin(x), cos(x+2.0), exp(-x**2)).
4. The rand function is entered with parentheses and a null argument (rand(0)) and returns a value between 0 and 1.
