Surely that is rsin²θ + rcos²θ = r. And that looks like rectangular coordinates; in polar coordinates that would simply be r = nLes Morgan wrote:So the equation for a circle is: sin(a) + cos(a) = 1 (polar coordinates) . . .

You are right there; cos for x and sin for y. It was after all during the Swinging Sixties that I was taught about that definition of sin/cos.Les Morgan wrote:. . . X component is cos(a) and Y is sin(a) for getting (X, Y). Therein, amongst other places, my mind went off track a bit. . . .
