2π is equal to a complete revolution around the unit circle, or 360°. What are the trig functions and how do they relate to the unit circle? The primary trig functions are sine, cosine and tangent. On the unit circle, sine corresponds to the y-value, and cosine to the x-...
Trig Functions Using the Unit Circle Now we are ready to see the definitions of the trig functions using the trig unit circle. Consider the last example where we have a right triangle {eq}OPR, {/eq} with {eq}P(x, y) {/eq} being a point on the circumference and {eq}\alpha {/eq...
Trigonometric Functions: The Unit Circle Section 4.2 Objectives Find a point on the unit circle given one coordinate and the quadrant in which the point lies. Determine the coordinates of a point on the unit circle given a point on the unit circle. State the sign of the sine or cosine valu...
Unit circle tangent & other trig functions You can find the unit circle tangent value directly if you remember the tangent definition: The ratio of the opposite and adjacent sides to an angle in a right-angled triangle. tanα=oppositeadjacenttanα=adjacentopposite As we learned from the pre...

The circle is divided into four quadrants, each separated by a right angle, or 90 degrees. At each of the lines dividing the quadrants, one of the trig functions equals zero, and the other equals either 1 or -1. Memorize the coordinates of these four points. Each quadrant is then ...
Furthermore, this Left-Hand Trick is going to help you not only to memorize the Unit Circle, but it is also going to allow you to evaluate or find all six trig functions!Additionally, as Khan Academy nicely states, the Unit Circle helps us to define sine, cosine and tangent functions ...
