EDIT 2/2/15: Added an example for finding the tangent line to a function.
Having trouble with the WeBWorK? First, don’t panic – it’s a lot to remember!! But do be prepared to put in some time re-learning stuff from Calculus I and II. I’ve picked out a few video resources for you that hit some of the most important techniques (I tried to find videos that were focussed on examples, rather than theory, since this is meant to be review).
Comments are welcome (just click the “leave a comment” button above).
- Like a video? Leave comment and let me know.
- Dislike a video (it wasn’t helpful/ it was confusing)? Let me know.
- Need help with another topic (like the product rule, or equations of tangent lines, or something else)? Let me know.
- Have a video or other resource to suggest? Let me know!
Derivatives: Equation of the tangent line to a curve (similar to Problem 2): This gives an example of finding the equation of a tangent line, starting with just the function and the x-value. (NOTE: In the video, the function is an exponential function, so the numbers running around the answer all tend to have e in them – this will not be the case in the WeBWorK problem, where you will find more familiar numbers in your answer).
Derivatives: The Chain Rule (similar to Problem 4): This video is short and sweet, a single example using the chain rule with a logarithmic function.
Integrals: U-Substitution (similar to Problems 5 & 6):
This video has three examples – the first two are most similar to what you will see in WeBWorK (the last one is a little trickier – but could be useful in the future):

Integration by Parts (similar to Problems 7 & 8)
This video also has a few examples – the first two will be most useful for the WeBWorK:
