This program will graph functions of the form y = f(x), functions of the form x = g(y), polar equations of the form r = r(t), where t is the angle, as well as parametric equations of the form x = x(t), y = y(t). Up to nine equations can be plotted. It also computes line integrals over these curves. You can use a mouse in this program.
