Propose a parametric representation of a spiral. Hint: Use the parametric representation of a circle. This is the parametric representation of a circle we are given : x = r * Cos(Theta) y = r * Sin (Theta) 0 <= Theta <= 2 Pi Nope, we are not given anything background on spirals. I am like super new at this graphics thingy. I've been searching around the net for 4 hours now, I did find a few answers but none taught me how to get the representation from a circle and I have no idea how they derive at the answer. All I know right now about this graphics thingy is : x and y are like coordinates. And that t or Theta in this case is kinda like a path or timeline where decides when coordinates of x and y starts and ends. I am thinking of making the radius a parameter and then slowly increasing it? x = u * Cos(Theta) y = u * Sin (Theta) 1 <= u <= 4 Something like that? Thats all I know, so help please?
