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
R2 = x2 + y2 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 (-π , π] or (-180° , 180°].
How to use the calculator
1 - Enter x and y and press the button "enter".
