WebJan 2, 2024 · Trigonometric Functions of an Angle. With the notation in Figure 3.1, we see that cos(t) = x and sin(t) = y. In this context, we often the cosine and sine circular functions because they are defined by points on the unit circle. Now we want to focus on the perspective the cosine and sine as functions of angles.
