## Rectangular and Polar Coordinates

Convert rectangular to polar two dimensional coordinates using a calculator.The rectangular coordinates (x,y) and polar coordinates (R,t) are related as follows.

**y = R sin t and x = R cos t**

**R**

^{2}= x^{2}+ y^{2}and tan t = y/xThe calculator finds R using R = sqrt(x

^{ 2}+ y

^{ 2}). Then finds the quadrant using the signs of x and y and solve any of the equations

for t such that t is in the range (-π , π] or (-180° , 180°].
