learning how to do Polar Coordinates and add them.

[tom234]

[attachment=7270] I was doing this example in HP27s Manual page 155.

It was quite a task to do it in HP Prime.

programmed this in:
I used a Matrix to input on the calculator line
polar_coordinates(rectangular_coordinates(polar_point(M2)))

on the calculator line as a function it worked.

Tried to make it a program it did not work:
#cas
PP_PC():=
BEGIN
polar_coordinates(rectangular_coordinates(polar_point(M2)))
END;
#end
It gives an answer that is totally wrong does the programmer mode treat Matrix differently and how so?
