WebThe Greek letter θ (theta) is used in math as a variable to represent a measured angle. For example, the symbol theta appears in the three main trigonometric functions: sine, cosine, and tangent as the input variable. cos(θ) In plain language, this represents the cosine function which takes in one argument represented by the variable θ.

We say that θ is in standard position if its initial side is the positive x -axis and its vertex is the origin (0, 0). Pick any point (x, y) on the terminal side of θ a distance r > 0 from the origin (see Figure 1.4.3 (c)). (Note that r = √x2 + y2. Why?) We then define the trigonometric functions of θ as follows:
