Does anyone have experience with a casio fx-9750 calculator? I'm trying to figure out how to convert rectangular to polar coordinates and visa versa. I have a casio fx-115 which does complex operations easily in both coordinate systems, but with the casio fx-9750 I can only figure out how to use rectangular coordinates in complex mode. My fx-115 will easily resolve an expression like: (9+5i) + (5[tex]\angle[/tex]45)

Does anyone know how I can do that with my Casio fx-9750?

Thanks a lot.
