3.1 Trig and Periodic Functions Unit Circle A unit circle is a circle of radius 1, with its center at the origin of a rectangular coordinate system. Equation: x2 + y2 = 1 In a unit circle, the radian measure of the central angle is equal to the length of the intercepted arc. If the angle, t, is a real number in radians, then

Dec 27, 2020 · A full circle is 2 π radians, since the circumference of a circle with a radius of 1 is 2 π. To convert an angle measurement in radians to degrees, multiply by 57.3. To convert an angle measurement in radians to degrees, multiply by 57.3.
x2+ y2= 1 That is, the unit circle with center at the origin (0,0) and the radius 1.
