Hi,

I generated a flower image like this:
    d = sqrt((x0-x)^2 + (y-y0)^2)
    r = Constant*[cos(angle)]^2......................imp.
    if (d <= r) { HIGH value} else{LOW value}

this gives me a flower image.

i would like to generate a smooth sine wave pattern
around the circle..... The wavy circle should go in and out..

Is there a std. equation of this curve  ?

thanks.
jas
