SUMMARY

The discussion focuses on creating a function for the TI-89 calculator that calculates the total resistance of multiple resistors in parallel. The user seeks to implement a method for accepting an undetermined number of resistor inputs, specifically using a list as an argument. The formula for calculating total resistance is established as 1/(1/R1 + 1/R2 + 1/R3 + ... + 1/Rn). Solutions proposed include utilizing lists or prompting user input in a loop to gather resistor values.

PREREQUISITES
  • Familiarity with TI-89 programming syntax
  • Understanding of parallel resistor calculations
  • Knowledge of list data structures in programming
  • Basic experience with user input handling in TI-89 functions

I'm trying to create a function that will calculate any amount of resistors in parallel but I do not know how to allow an undetermined amount of arguments for input (rather than a fixed amount). Basically it would look like this pll(R1,R2,R3,Rn) where Rn would be anything from R2 to R1000 or whatever. The equation is 1/(1/R1 + 1/R2 + 1/R3 + 1/Rn).

Either use a list as an argument, or ask the user to input resistors in a loop
 
How do I use a list as an argument?
