Polar and Rectangular conversion
rectangular_coordinates((sqrt(2)),(π/4)) ==> [1,1]
polar_coordinates(1,1) ==> [sqrt(2),(3/4)*π] polar_coordinates([1,1]) ==> [sqrt(2),(3/4)*π] polar_coordinates() expects a point, and returns a vector. rectangular_coordinates() expects a vector and returns a vector. This is confusing for infrequent users of these commands. The polar_coordinates() command can lead to an incorrect result, if a vector is supplied as the argument, such as might be the case if the result of rectangular_coordinates() was being reused there. NOTE: I was using the emulator, and I have been noticing some odd behaviors (including the above). After performing a reset, I am now getting the same result from polar_coordinates() whether or not a point or vector is used. I apologize for this diversion! Dale
