Formulas for angles in circles

WebJul 13, 2024 · By this symmetry, we can see the coordinates of the point on the unit circle at an angle of 60 degrees will be (1 2, √3 2), giving cos(π 3) = 1 2 and sin(π 3) = √3 2 We have now found the cosine and sine values for all the commonly encountered angles in the first quadrant of the unit circle. WebThe angle formed outside of the circle is always equal to the the far arc minus the near arc divided by 2.
