If you miss a class or just need a little more of an explanation with a certain topic, have a look at these …
- No calculator at home? Try this online scientific calculator.
- HippoCampus — EXCELLENT general resource!! Links to many math and calculus topics; each one includes a mini-lesson with examples and audio.
- Here’s an amazing YouTube collection of videos that demonstrates dozens of examples of different math topics, including things we cover in every one of our high school math courses!! DEFINITELY worth taking a look through on your own, and I’ll pick out and highlight a few useful ones below for each course.

Trig Identities:
- A short video … www.youtube.com/watch?v=9uoKutwuCio
- A few tips and examples … www.intmath.com/Analytic-trigonometry/
Composition of Functions – www.youtube.com/watch?v=S4AEZElTPDo; note some more of his math videos listed to the right on the YouTube page, including one on graphing piecewise functions
Three simple calculus videos, where students use simple drawings, with explanations, to illustrate what calculus is.
A few selections on the concept of limits … (also, check out HippoCampus above)
- “Introduction to Limits” (Youtube) … again, pretty good basic explanations here if you don’t mind all the colours, and a few of his other videos are also helpful here
- “What is a Limit?” (Youtube) … this video and a few others that follow it are worth a look, as they go through different examples involving calculations
- “Limits at Infinity” (Youtube) … shows a couple of worked examples
- “Limits at Infinity With Radicals” (Youtube) … same as above, but with more difficult examples
- Secant to Tangent Applet — easy to use; has some examples, and you can enter your own functions as well
- Tangent Lines and Rates of Change — contains several examples worth a look
- Another really good, interactive tutorial can be found here.
- Tutorials for the Calculus Phobe — a nice treatment of the basics: limits and derivatives.
- Here’s a collection of some videos on the Chain Rule and implicit differentiation.
Math 521B
Here are a couple of interesting websites about polygons and the sum of their interior/exterior angles:
- Mathisfun.com (sure it is!) — a nice explanation of the Interior Angle Sum Theorem (with links at the bottom of the page to other polygon-related pages)
- Keymath.com — the Exterior Angle Sum Theorem (with polygons that you can manipulate)
A couple of videos involving rational expressions and equations:
Here are some examples of simplifying, multiplying/dividing, and adding/subtracting REs.
