Equation 2d curve help!!!!


/* For cylindrical coordinate system, enter parametric equation

/* in terms of t (which will vary from 0 to 1) for r, theta and z

/* For example: for a circle in x-y plane, centered at origin

/* and radius = 4, the parametric equations will be:

/*&n bsp; r = 4

/* theta = t * 360

/*&n bsp; z = 0

/*-------------------------------------------------------- -----------

theta = t*360*40

r = theta^.5

z = 0

40 is the amount of circles .. the rest is from that guys equation :)

hope this helps.
