**How To Find Exact Value Of Trig Functions With Unit Circle**. For a unit circle having the center at the origin(0, 0), the radius of 1 unit, if the radius is inclined at an angle θ and the endpoint of the radius vector is (x, y), then cosθ = x and sinθ = y. A diagram of the unit circle is shown below:

### Remember That The Angle In The First Quadrant Is Often Referred To As The ^Reference _ Angle.

Today, trigonometry has much broader applications than that of the. It is useful to memorize the exact values of the sine and cosine functions when x is equal to 0, 6. For a unit circle having the center at the origin(0, 0), the radius of 1 unit, if the radius is inclined at an angle θ and the endpoint of the radius vector is (x, y), then cosθ = x and sinθ = y.

### These Unit Circle Ratios Work Regardless Of The Size Of The Circle Or Triangle.

Solving linear trig equations (for angles not on the unit circle) when solving a trig equation for solutions outside the first quadrant it is important to review how to find the ^matching _ angle in the other 3 quadrants. Using the unit circle and the identities, find the six trig functions for the following angles. Use special triangles or the unit circle.
