This is a second test of the HWEB system of documentation. The compiler ought to produce some nice HTML code for this example as well.
Consider the equation Ax+By+C = 0, with (A, B, C) our independent variables. Suppose we have two points on this line; call them (x1, y1) and (x2, y2). We want to find a number of other points xi and yi on this line. We can do this by solving the magic equation
for some magic Z. It might also help to consider u = sinx rather than simply x, I dunno.
x n +y n = Z n i i
