HP50G Complex numbers with square roots

Click For Summary
SUMMARY

The discussion centers on using the HP50G calculator to work with complex numbers, specifically how to input them from the stack in RPN mode. The user initially struggled with entering expressions like 6^0.5 + 2i without typing each number manually. The solution involved utilizing the HIST > ECHO command to select items directly from the stack, streamlining the process of creating complex numbers.

PREREQUISITES
  • Familiarity with HP50G calculator functions
  • Understanding of RPN (Reverse Polish Notation) mode
  • Basic knowledge of complex number representation
  • Experience with using the stack in HP calculators
NEXT STEPS
  • Explore advanced HP50G functions for complex number calculations
  • Learn about stack manipulation techniques in RPN mode
  • Investigate other commands like HIST and ECHO for efficient data retrieval
  • Study complex number operations and their applications in HP calculators
USEFUL FOR

Users of the HP50G calculator, particularly those working with complex numbers and RPN mode, as well as educators and students in mathematics or engineering fields.

Hi, I recently bought an HP50G, and I'm having trouble figuring out how to get numbers from the stack into a complex number. Could anyone help?

For example, for 1+2i, I know I'd enter it as (1,2). But when I have something like 6^0.5+2i, I don't want to type the numbers out.

Thanks

Edit: I'm using RPN mode. I've tried a few searches and haven't come up with anything.

I got it figured out. I needed to use HIST > ECHO to select an item from the stack.
