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.

The formula for the unit circle relates the coordinates of any point on the unit circle to sine and cosine. According to the formula, the x coordinate of a point on the unit circle is cos(θ) c o s (θ) and the y coordinate of a point on the unit circle is sin(θ) s i n (θ) where Θ represents the measure of an angle that goes counter ...
The Unit Circle The two historical perspectives of trigonometry incorporate different methods for introducing the trigonometric functions. Our first introduction to these functions is based on the unit circle. Consider the unit circle given by Unit circle as shown in Figure 4.20. FIGURE 4.20
Unit Circle. 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.

Let us learn more about cotangent by learning its definition, cot x formula, its domain, range, graph, derivative, and integral. Also, we will see what are the values of cotangent on a unit circle.
Defining the Functions Recall, the graph of the equation x y2 1 is the unit circle. The graph of this equation is used to generate the trigonometric functions. Suppose we place the vertex of an angle with measure T at the origin so that one of its sides lies along the positive x-axis and the other side intersects the unit circle at the point (x,y)
