Why Take This Course?
Trigonometry is one of the most-used branches of mathematics. For instance, it is used in construction to calculate roof pitch. It is used in physics to calculate the strength of forces in various directions. Pretty much any problem in the universe that involves a triangle or cyclical motion can be solved using trigonometry. In PreCalculus A, we explore the applications of trigonometry, vectors, and complex numbers with projects and in-class discussions that will allow you to think creatively and apply math concepts to solve relevant problems.
