Approximating Integrals in Maple 

To get started call the "Student[Calculus1]" package.

The "ApproximateInt" command is used to approximate an integral numerically.  The first input to the command is f(x), the function whose integral we want to estimate.  The second input is the interval over which you want to approximate the integral.  The third input is the number of sub-intervals that you want to use for the approximation.  The fourth input is the method that you want to use for the approximation.  For now, we'll use the left, right, midpoint, and trapezoid methods, but we'll talk later about a few others.  Finally, the output option specifies how you want Maple to output the result.  For now, we'll use the output=plot and output=value options.
