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.
