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 ... WebThere's nothing wrong with the original answer of 1/sqrt (2), but this is just more 'proper', if you will. 2) Arcsin is restricted to the 1st and 4th quadrant because the value of sine goes from all possible values that way. Think about the unit circle. In quadrants 1 and 2 sin will have the same value.
