Welcome! If you are looking for help in using your algebra and trigonometry skills for physics, you have come to the right place.

This is a collection of tutorials on the techniques in algebra and trigonometry needed for solving problems in college introductory physics courses. The tutorials are not intended to be replacements for the math courses that you should have had as prerequisites; they are for "brushing up" on skills that were never quite mastered, or perhaps learned a very long time ago and forgotten.
