Find reference number unit circle

WebVIDEO ANSWER: So in this problem we're asked to find the reference number for T equals for And T. equals 3.6. So first of all, what's a reference number? Well, a reference number. Reference number is the shortest distance alone. The unit circle WebThe general equation of a circle is (x - a) 2 + (y - b) 2 = r 2, which represents a circle having the center (a, b) and the radius r. This equation of a circle is simplified to represent the equation of a unit circle. A unit circle is formed with its center at the point (0, 0), which is the origin of the coordinate axes. and a radius of 1 unit.
