Limits Toward Infinity in Rational Functions

Grade Level Grade Level

  • 12th Grade

In this lesson, students will explore the puzzling ideas behind Grandi's series in order to construct an idea of how the sum of an infinite number of terms in a sequence can be evaluated. After exploring Grandi's series, students take a closer look at limits of rational functions as their values of... Read more »

Grade Level Grade Level

  • 12th Grade

This lesson is a follow-up to I Sub, U-Sub, We All Sub. In the previous lesson, students worked with the teacher to create an anchor chart of what "worked" and what "didn't work" for anti-differentiating derivatives of functions. The goal of this lesson is to build upon that knowledge in order for students... Read more »
