Welcome to Trigonometry

The following covers material commonly seen in a College level Trigonometry course or a high school Algebra 2/Trigonometry course.  I attempted to provide comprehensive introductions to each topic, as well as some example problems.  In some cases I give additional material to help provide deeper insight.  I suggest reading through the introduction material before looking at the examples.  The best way to have long term success in calculus is to understand the concepts.  Any particular example problem may still be challenging, but a sound understanding of the concepts should be the main goal for learning the material.  Enjoy, and always feel free to reach out for questions, corrections, or private tutoring!
