      9th grade is a good time to introduce Right Triangle Trigonometry and the definitions of Cosine, Sine and Tangent as they relate to a right triangle. Diagrams and numerical examples are a great way to start, showing the "special triangles" like 45-45-90 and 30-60-90 as well.

      Hope that helps!
