Something to talk about - ReviewExplicit vs. RecursiveWhat’s the difference?
Explicit: names the first term IN the equation Recursive: Names the term when x = 1 Uses the PREVIOUS term to name the new termSlide4
Something to talk about - reviewAn EXPLICIT equation has ONE PART
n-1First term common ratioA RECURSIVE equation has TWO PARTS and a BRACKET
Slide5
Something to talk about - ReviewExplicit and Recursive Formulas: So how do we write them?Explicit
Start with the first termWhat is the change?If it’s a COMMON DIFFERENCE (adding by the same number) your equation will include addition – it’s LINEARExample: RSG 1.1 – 8cSlide6
Something to talk about - ReviewExplicit and Recursive Formulas: So how do we write them?Explicit
If it’s a COMMON RATIO (multiplying by the same number), your equation will include MULTIPLICATION AND AN EXPONENT – it’s EXPONENTIALExample: RSG 1.1 – 8aSlide7
Something to talk about: ReviewRecursive:Find the function when x = 1
Find the change RELATIVE TO f(x) or yIf it’s a common difference (adding by a constant rate), your second equation will look like:TERM YOU WANT = PREVIOUS TERM + COMMON DIFFERENCEExample: RSG 1.1 – 8cSlide8
