Find polar coordinates

How to: Given polar coordinates, convert to rectangular coordinates.

  1. Given the polar coordinate (r,θ), write x=rcosθ and y=rsinθ.
  2. Evaluate cosθ and sinθ.
  3. Multiply cosθ by r to find the x-coordinate of the rectangular form.
  4. Multiply sinθ by r to find the y-coordinate of the rectangular form.
