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/x

The 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

x = R cos t or y = R sin t

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