Calculators Plotting modulus functions in TI-89 Titanium

  1. Oct 5, 2012 #1
    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 :)
