Math Help

[~Zero~]

So yea, I need some math help. I totally forget how to change polar coordinates into rectangular coordinates. One of the problems I had was this

Change into rectangular coordinates

rcosθ = 7

If you could also show me how to change rectangular coordinates into polar I would greatly appreicate it. Not entirely sure if this is the right place for this topic either.

Re: Math Help

x = rcos(theta)

y = rsin(theta)

Have fun.

Also, r^2 = x^2 + y^2. That should be all you ever need.
