8th period: Please watch this video to introduce the big idea behind today’s lesson (late in the video, the term “gradient” refers to the slope of the line tangent to the curve at a point), then watch this video from 14:30 to 18:15 for some examples of how to use this formula. Your homework will be the same as below.
We expanded on compound interest today, extending the concept to the idea of “compounding continuously,” which in turn led us to the fascinating mathematical constant of e. If you’re interested in learning more about e, click the link!
- Homework: HW 9.10 – Compounding Continuously
- Lesson video 1 – The is a Numberphile video explaining what e is and some of the interesting things it does.
- Lesson video 2 – Skip to the 14:30 mark for information on compounding continuously, but the first bit is a great review of other compound interest problems.
