The unit circle can be used to find sin and cos values for angles between 0 ° and. Give exact values for the y-coordinate of each point. Find the exact value of each of the remaining trigonometric functions. Trigonometry Review - Johnson County Community College. Step 2 Find the value of the trigonometric function for Step 3 Using the quadrant in which the terminal side . Reference Angles: - In order to find the values of trig functions. If we continue moving round the "unit circle" (the circle with radius 1 that we have been drawing angles on above), then we find that sin(390°) is also 0.5. For any angle Sin, Cos and Tan - Mathematics A-Level Revision. The four quadrants are labeled I, II, III, and IV. We label these quadrants to mimic the direction a positive angle would sweep. sss Using the formula s=rts=rts=rt, and knowing that r=1r=1r=1, we see that for a unit circle, s=ts=ts=t Recall that the x- and y-axes divide the coordinate plane into four quarters called quadrants.
