Methods for Numerical Integration
This applet allows a person to test several numerical integration approximation methods by having the user fill out the
left and right endpoint fields, type in the formula, select the method, and pressing the calculate button. For example try
typing in -1 for the left endpoint, 1 for the right endpoint, and y=x^2 for the formula then press calculate.
For each method selected, the estimated integral for that method will appear in the text area at the bottom. Certain
functions will also appear on the graph on the left. The java graph class is still experimental and does not use equal
stretch principles. y = x2 from -1 to 1 will appear the same as y = x2 from -100 to 100.
