Web2 de jan. de 2024 · Exercise 1.2.6. We know that the equation for the unit circle is x2 + y2 = 1. We also know that if t is an real number, then the terminal point of the arc determined by t is the point (cos(t), sin(t)) and that this point lies on the unit circle. Use this information to develop an identity involving cos(t) and sin(t).
