Propose a parametric representation of a spiral.(adsbygoogle = window.adsbygoogle || []).push({});

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?
