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.
