In mathematics, a unit circle is a circle with a radius of one. Frequently, especially in trigonometry, the unit circle is the circle of radius one centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.

What is the unit circle and what is it used for?

The unit circle is used to understand sines and cosines of angles found in right triangles. The unit circle has a center at the origin (0,0) and a radius of one unit. Angles are measured starting from the positive x-axis in quadrant I and continue around the unit circle.

What is sin in the unit circle?

The Unit Circle. The point of the unit circle is that it makes other parts of the mathematics easier and neater. For instance, in the unit circle, for any angle θ, the trig values for sine and cosine are clearly nothing more than sin(θ) = y and cos(θ) = x.

Why is it important to know the unit circle?

The circumfrence of the unit circle is 2Π . An arc of the unit circle has the same length as the measure of the central angle that intercepts that arc. Also, because the radius of the unit circle is one, the trigonometric functions sine and cosine have special relevance for the unit circle.

Where is negative pi to pi on the unit circle?

The interval (−π2,π2) is the right half of the unit circle. Negative angles rotate clockwise, so this means that −π2 would rotate π2 clockwise, ending up on the lower y-axis (or as you said, where 3π2 is located) .Mar 13, 2014

Sine, Cosine and Tangent. Because the radius is 1, we can directly measure sine, cosine and tangent. unit circle center angle 0. What happens when the angle, θ, is 0°? cos 0° = 1, sin 0° = 0 and tan 0° = 0. unit circle center angle 90. What happens when θ is 90°? cos 90° = 0, sin 90° = 1 and tan 90° is undefined ...
