I have a unit circle:(adsbygoogle = window.adsbygoogle || []).push({});

x^2+y^2 <= 1

And i'm asked to convert it to a square with verticies (0,0),(0,1),(1,0),(1,1).

Now obviously I have to do this in polar coordinates, so I've rewritten the equation as:

x = cos t

y = sin t

I'm sort of drawing a blank after setting up these equations. How can I convert this curve into straight lines. Any suggestions?
