   What is a unit circle centered at the origin?

   • The Unit Circle: A circle centered at the origin with a radius of 1 unit is called the unit circle whose equation is given by x 2 + y 2 = 1. So far in this text, we have seen two groups of definitions for the trigonometric functions. In Section 6.4 we saw the Right Triangle Definitions of the Trigonometric functions of acute angles .

   What is a unit circle with a radius of 1?

   • The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here. Because the radius is 1, we can directly measure sine, cosine and tangent. What happens when the angle, θ, is 0°?

   What is the equation of a unit circle?

   • 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. Hence the equation of the unit circle is (x - 0) 2 + (y - 0) 2 = 1 2. This is simplified to obtain the equation of a unit circle.

   What is the unit circle. In trigonometry, the unit circle is a circle with of radius 1 that is centered at the origin of the Cartesian coordinate plane. The unit circle helps us generalize trigonometric functions, making it easier for us to work with them since it lets us find sine and cosine values given a point on the unit circle.
