# Physics 20 Fall 2014

## Discussion Notes

### Week 1

- Lecture Summary:
- Crash course in derivative (Khan Academy Power Rule) and integrals (Khan Academy integrals) of polynomials. Overview of vectors, dot product and cross product. Discussion of the position vector, velocity vector and acceleration vector.

(**Note**: For those strugglging with the calculus we have done so far I reccomend watching the entire subseries I linked in this week's "Lecture Summary." Note that these are just a narrow topic in a broad list of topics about derivatives and integrals Khan Academy covers. For the entire course provided by Khan Academy visit: here for differential calculus, most important to your understanding for this course would be "Taking derivatives." And here for integral calculus, most important to your understanding for this course would be "Integrals." Typically one learns about derivates first and then moves onto integrals, sometimes called anti-derivates. I would reccomend this route for those just starting.)
