Answer. A unit circle is a circle that is centered at the origin and has radius 1, as shown below. If (x, y) are the coordinates of a point on the circle, then you can see from the right triangle in the drawing and the Pythagorean Theorem that x2 + y2 = 1. This is the equation of the unit circle.

Which is why trigonometric functions have unique values for the unit circle. Sine, Cosine, Tangent. When sin, cos, and tan are plotted on a graph, their measurements become visible. Sin, Cos, Tan Unit Circle Chart at 0° If the tangent start from x-axis on unit circle then Tan θ = 0. Sine (sin): sin(0°) = 0; Cosine (cos): cos(0°) = 1

The hierarchy consists of three levels as follows: Level 1 (Department) - identifies a particular department or agency; Level 2 TAN Prefix - identifies a unit such as region, branch or sector; and. Level 3 TAN Prefix - identifies a specific cost centre and is associated to a DTEA. Prepaid airfare and rail transactions are charged to the DTEA.
How to Use the Unit Circle in Trigonometry HowStuffWorks
To define our trigonometric functions, we begin by drawing a unit circle, a circle centered at the origin with radius 1, as shown in Figure 13.2.2. The angle (in radians) that t intercepts forms an arc of length s. Using the formula s = rt, and knowing that r = 1, we see that for a unit circle, s = t.

The unit circle with tangent is also known as the trigonometric circle of the tangent function. It gives the values of the trigonometric function "tan" for different standard angles that lie between 0° and 360°. The standard angles between 0° and 360° are tabulated below both in terms of degrees and radians.
