How do I convert coordinates on a Casio fx-9750 calculator?

In summary, the conversation is about the Casio fx-9750 calculator and its ability to convert rectangular to polar coordinates and vice versa. The fx-115 model is able to easily perform complex operations in both coordinate systems, while the fx-9750 can only do so in complex mode. There is a workaround involving using the rectangular value, switching to polar, and adding the polar expression. The speakers also discuss the efficiency and ease of use of different calculator models for operations like base conversion and logic. Further details and instructions can be found in the manual on page 48.

Hi all
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.

Enter the rectangular value, switch to polar, add the polar expression. At least that's as far as I got with it before deciding I didn't like it and went back to the 115ms.

Option - F3 (complex), Option - F6 (next), F5 (angle)

I don't know why they some operations require so many more keystrokes on graphing calcs compared to other models. The TI-36X is another example that is simpler than the graphic TI-89 for operations like base conversion and logic.
