Unit 2  Objective 2  Defining Trigonometric
Functions
There are six possible ratios of two sides of a triangle. These names are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). Because these ratios depend on the size an angle Q, they are written sin Q, cos Q, tan Q, cot Q, sec Q, and csc Q.
