A type of circle is the unit circle. Let us find out what do we mean by a unit circle? Definition: The meaning of unit, as we all know is 1. Therefore it can easily be made out that a unit circle is a circle with a radius of 1. The following figure represents the circle with ...
The unit circle chart in radians is given in the diagram below. It represents a total angle of 2 radians or 360. The unit circle is divided into four quadrants by the intersection of x-axis and y-axis. The points which represent the angles $\frac{\pi}{0},\; \frac{\pi}{6},\; ...
To compute the unit circle with tangent values we just use the identity tan x = (sin x)/(cos x). Learn more about the unit circle with tangent by computing the table of values and learn how to graph the tangent function using the unit circle.
Similarly, we can extend and find the radians for all the unit circle quadrants. The numbers 1/2, 1/√2, √3/2, 0, 1 repeat along with the sign in all 4 quadrants. Unit Circle in Complex Plane A unit circle consists of all complex numbers of absolute value as 1. Therefore, it ...

On the unit circle the functions take a particularly simple form. For example,sin θ = y1 = y.cos θ = x1 = x.The value of sin θ is the y-coördinate of the endpoint of the unit radius. The value of cos θ is the x-coördinate....
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.
