Title Area Under a Curve
Description This program uses the Romberg algorithm to find area under a curve. I have tested other programs for speed and accuracy but found mine to be superior in both. The user can set accuracy to a set number a decimal places. It also shows an estimate of the answer as it zeros in on the exact answer. As far time goes, here are some times for the 84 silver editon and 9 decimal place accuracy in radian mode. Yes, 9 decimal places. e^(-x) from 0x-50x takes 25 seconds. sin(x), 0 x-10pi x takes 1 second. cos(x+32)+2sin(x) from 0-10 takes 25 seconds.
