The unit circle with tangent gives the values of the tangent function (which is usually referred to as "tan") for different standard angles from 0° to 360°. Usually, the general unit circle gives the values of sin (sine function) and cos (cosine function).
Using the unit circle diagram, draw a line “tangent” to the unit circle where the hypotenuse contacts the unit circle. This line is at right angles to the hypotenuse at the unit circle and touches the unit circle only at that point (the tangent point).
This colored unit circle chart shows the true values of sine, cosine and tangent (sin, cos, tan) for the special angles 30, 45, 60.
Sine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same. no matter how big or small the triangle is.
What is the unit circle definition of the trigonometric functions? The unit circle definition allows us to extend the domain of sine and cosine to all real numbers. The process for determining the sine/cosine of any angle θ is as follows: Starting from ( 1, 0)

UNIT CIRCLE. A unit circle has a center at \((0,0)\) and radius \(1\). Form the angle with measure \(t\) with initial side coincident with the \(x\)-axis. Let \((x,y)\) be point where the terminal side of the angle and unit circle meet. Then \((x,y)=(\cos t,\sin t)\). Further, \(\tan t=\dfrac{\sin t}{\cos t}\).
The unit circle is a circle with a radius of one unit. Learn the definition, equation of unit circle, applications in trigonometry along with examples and more.
Unit circle: sine, cosine, tangent. The unit circle provides a simple way to define trigonometric functions. This is because of the relationships between the functions, the unit circle, and their right triangle definitions. For reference, the right triangle definitions of sine and cosine are listed below:
