The Math IIC test rigorously covers trigonometry, which is one of the major differences between it and the Math IC test. If you have only a rudimentary understanding of trigonometry, the IIC test might not be the best choice for you.

But if you’ve taken a trigonometry class, the Math IIC test is the place to be (especially since it has that great scoring curve). In this chapter we’ll explain how to deal with radians, and review all the basic trigonometric functions, including inverse trigonometric functions, graphing trigonometric functions, and the use of trigonometry in oblique triangles.
