WebUnit Circle - Key takeaways. The unit circle has a radius of 1 and a centre at the origin. The formula for the unit circle is x 2 + y 2 = 1. The unit circle can be used to find sin and cos values for angles between 0 ° and 360 ° or 0 and 2𝜋 radians. The x-coordinate of points on the circumference of the unit circle represents the cos value ... Web14 de jun. de 2024 · We know that cos t is the x -coordinate of the corresponding point on the unit circle and sin t is the y -coordinate of the corresponding point on the unit circle. So: x = cos t = 1 2 y = sin t = √3 2. Try It 2.2.1. A certain angle t corresponds to a point on the unit circle at ( − √2 2, √2 2) as shown in Figure 2.2.5.
