Welcome! I will progressively update this webpage throughout the course. So visit regularly for important worksheets, links, study tips, and extra exam help and problems. For now, here is the course syllabus and the diagnostic test with solutions you took during the first lecture.

### Resources:

If you don't have a graphing calculator, wolfram alpha is very helpful. Even if you have one, it's still a great way to check your work.
For extra help and review, visit khan academy's lectures on various topics.

### Homework:
