SUMMARY

The Casio fx-9750 calculator can convert rectangular coordinates to polar coordinates, but the process requires multiple keystrokes compared to simpler models like the Casio fx-115. Users can perform operations by entering the rectangular value, switching to polar mode, and then adding the polar expression. Key operations involve navigating through the complex mode using Option - F3, followed by Option - F6 and F5 for angle adjustments. Detailed instructions are available on page 48 of the calculator's manual under the "coordinate conversion" section.

PREREQUISITES
  • Familiarity with Casio fx-9750 calculator functions
  • Understanding of rectangular and polar coordinate systems
  • Basic knowledge of complex number operations
  • Access to the Casio fx-9750 manual for reference
NEXT STEPS
  • Review the Casio fx-9750 manual, specifically page 48 on coordinate conversion
  • Practice converting between rectangular and polar coordinates using the fx-9750
  • Explore additional functions of the Casio fx-9750 for complex number calculations
  • Compare the Casio fx-9750 with other calculators like the TI-36X and TI-89 for efficiency in operations
USEFUL FOR

Students, engineers, and professionals who utilize the Casio fx-9750 for mathematical calculations, particularly those involving complex numbers and coordinate conversions.

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\angle45)
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.
