Hi Everyone,
Below is the assignment for this week.
One thing to note about the notes … remember that the limit of a function is the number it APPROACHES, not the necessarily the number it reaches. With trig functions, we refer to their graphs (sorry, Christopher) which I have drawn in the notes.
Remember, we cannot divide by zero so we have to use our algebra skills to find a work-around. With Trig Functions, one of the key ideas is that the limit as Θ approaches zero of (Sin Θ)/Θ is 1. The graph is in the notes. But we try to make other limits looks like (Sin Θ)/Θ because we know the answer to that is 1 … read through the notes, follow the helpful links, read your text … and give me a call!
So, here is what I would like you to do:
- Read these notes: Limits of Trig FUNctions
- Read Section 7.1 Pages 302 – 306 in your text and check out the Helpful Links below
- Do the Assignment for 7.1 from here: Chapter 7 Assignments and here are the 7 point 1 worked out solutions from the answer book that is usually on my desk
- When you are ready for the 7.1 “quiz”, send me an email and I will send it to you. Deadline will be April 29th (ish).
