- Course Planner this shows the tentative plan for lectures and my recommended due dates for WebAssign.
- You Tube Playlist (I usually post Lectures soon after they're given).
- Wolfram Alpha is a nice math tool. I use it to check integrals, derivatives, ugly numbers and graphs.
- WebAssign homework with immediate feedback.
- You Tube Playlist from 2015 course (you are not expected to watch these).

These notes are from a previous year. I do not plan to post new notes this year, however, I do plan to teach the topics in a rather different order and there are bits here and there I will add and others I will completely skip. In any event, I would like for you to read the Lectures I assign in the Missions.

What I want is simple: I want you to understand what I cover in lecture and what I assign you in the homework as best you can. I want you to understand the physical concepts and I want you to be capable of applying mathematical techniques to unravel interesting word problems. In a nut-shell I want you to learn mathematically-aided problem solving; this is the heart of physics. I'm always happy to hear your questions about physics or math in office hours. However, I would enourage you to form study groups with serious students, teaching each other physics will engrain the thinking much more deeply. Personally, I could do physics before I tutored it, but I only understood physics once I tried to communicate it to others. By the way, there are no tutors for this course. Even if someone in the Math Help Center was willing, I would strongly discourage you seeking their help. The process of not understanding and then working and working and working until the break-through is an integral part of your academic maturing. If you just get answers from others then you will never properly "level-up". That time you get nothing done but are working is not lost, it is part of the process. That said, I do not assign grades on process, graduation date, scholarship qualification, pick your favorite club and/or university activity getting in the way scheduling, or ability. I will assign grades on the basis of what you write in the tests primarily. You should think about how you will prove to me you understand physics. Effort is necessary, but it may not be sufficient. Physics is worth the effort. If not for the content, then for the sake of the problem solving. I hope you all succeed this year!

- on monkeys and shooting
- on why the cross product has the formula it does. Given two vectors A and B I find the formula for another vector C which is perpendicular to both A and B. Of course there are infinitely many choices but we see one interesting choice is precisely what we call the
**cross product**of A and B; C = A x B. Notice that if the vectors had 4 components then the solution would have had two free parameters and we would find a whole plane of vectors which were perpendicular to A and B. This is why three dimensions are special, the orthogonal complement of the plane spanned by A and B is simply a normal line which points along the cross product. (don't worry if you don't get all the jargon in that last sentence, I'm using linear algebra terminology since my point is an algebraic one). - summary notes on vectors and the calculus of space curves.
