In this lesson, we will define the six trigonometric functions of angle θ. The six trigonometric functions of angle θ are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). We will learn how to find the function values of an angle given a point on its terminal side. Additionally, we will learn how to find the function values of an angle given its terminal side.
