Calculus Summer Assignment and Pre-Test over prerequisite pre-calculus skills

Created by
Locus Focus
This ”Summer Assignment” or Back to School "First Assignment" is an excellent review of the math skills before starting calculus. This assignment is useful because: ⋆ Students/Parents/Teachers like to know if students are ready for calculus early ⋆ Student preparation: While students are fresh from summer, they are more likely to ask about things that they have forgotten about because they’re not tired from the year yet. ⋆ The quiz that comes with this product is a good indicator of who in your

Created by
Locus Focus
This is PowerPoint™ presentation of 13 examples and homework assignment of 15 practice questions. The lesson starts with Vertical Asymptotes in which there are 7 examples. Examples are given both graphically and algebraically and where the limit on both sides of the vertical asymptote equal each other. Then in part 2, Horizontal Asymptotes, we talk about end behavior and hit exponential functions, rational functions, and “other” functions that may have two horizontal asymptotes. ContentsPowerP
