Convert Rectangular to Polar Coordinates - Calculator


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

R2 = x2 + y2 and tan t = y/x

polar-rectangular conversion of coordinates.

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 (-π , π] or (-180 , 180].
