Plotting modulus functions in TI-89 Titanium

Click For Summary
SUMMARY

To plot modulus functions on the TI-89 Titanium, users must utilize the abs function instead of mod, as the latter generates an error message indicating 'Too few arguments'. The mod() function is primarily used to return the remainder of a division operation, such as 18 mod 3 yielding 0 and 19 mod 3 yielding 1. Understanding the distinction between these functions is crucial for effective mathematical programming on the TI-89 Titanium.

PREREQUISITES
  • Familiarity with the TI-89 Titanium calculator interface
  • Understanding of mathematical functions and their syntax
  • Basic knowledge of programming concepts related to modulus operations
  • Experience with graphing functions on calculators
NEXT STEPS
  • Research the use of abs() for plotting absolute value functions on the TI-89 Titanium
  • Explore advanced applications of the mod() function in programming
  • Learn about graphing piecewise functions on the TI-89 Titanium
  • Investigate the differences between mod() and other mathematical functions in programming
USEFUL FOR

Students, educators, and programmers who utilize the TI-89 Titanium for mathematical computations and graphing, particularly those interested in understanding modulus functions and their applications.

How do I plot modulus functions in TI-89 Titanium? When I enter y1(x)=mod(x), in the y= editor, an error message turns up saying 'Too few arguments'.

Problem solved! You type abs for modulus functions not mod.
Next question: What do you use mod for?

mod() basically returns the remainder after a division. For example, 18 mod 3 returns 0, but 19 mod 3 returns 1. The arguments would be something like mod(#,base). Mods have some pretty cool uses in programming and mathematics :)
