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...
