This is a two page notes outline for an introduction to trigonometry that I use for my high school physics course. This gives students a basic overview of the SIN, COS, and TAN relationships for right triangles that students will need to work with vectors in a first year physics course. An excellent tutorial for basic trigonometry! You can teach all the trig they need for physics in one 40 minute block. Includes examples and practice for two types of trig problems.
