Rectangular to Polar

d R ³´ P
d ! displays the R ³´ P menu, which has functions for converting coordinates
between rectangular (x,y) and polar (r,q) format. Set Angle mode, as necessary, before
starting calculations.

Example
Convert polar coordinates (r,q) = (5,30) into rectangular coordinates. Then convert
rectangular coordinates ( x , y ) = (3,4) into polar coordinates. Round decimal results to
one decimal place.
