A calculator to find the exact value of a coterminal angle to a given trigonometric angle. Since cos θ is negative, it means θ is in the second and third quadrants. We can find those associated with the angles 30°, 45° and 60° using sohcahtoa on isosceles and equilateral triangles.

### Now That We Have An Idea Of How To Handle Trig Ratios, The Best Way To Get Comfortable With Them Is To Solve Some Trigonometry Problems.

Use special triangles, the unit circle, or a calculator to find values for the function at 30°=5 6 radian intervals. Sin(x), cos(x), tan(x), cot(x), sec(x) and csc(x) of a given angle. Sin, cos and tan values for 30°, 45° and 60° should be recalled easily.

### Find Exact Value Of Trigonometry Functions Using The Unit Circle.

Sin θ = y/r, cos θ = x/r, tan θ = y/x. For example sin 30° = ½, tan 45° = 1. Here's the table of these special trig values in both degrees and radians:

### Calculates The Trigonometric Functions Given The Angle In Radians.

Since cos θ is negative, it means θ is in the second and third quadrants. Function sinθ (sine) cosθ (cosine) tanθ (tangen) sinθ cosθ tanθ cscθ (cosecant) secθ. We have to find the values of six trig functions of {eq}(\theta) {/eq}.
