This book on Basic Trigonometry is different from most because the goals here are (a) to start from facts we know and (b) not go everywhere and do everything, but to make sure that we have the skills to actually solve problems involving trigonometry from our field of study, which is usually not mathematics.

It has been the author's experience that trigonometry is usually taught so completely abstractly that it seems to start nowhere, end nowhere, take up a full semester of study and in the end many students cannot apply this knowledge to their studies. Here we will stay focused on learning the basics of trigonometry and solving problems.

Trigonometry is the study of the properties of right triangles. Remember that a right triangle is a triangle with a right or 90° angle. Right triangles are everywhere and so anything that can help us with them is useful.
