Now, assume the two legs both have length 1. Then, by the Pythagorean theorem, the length of the hypotenuse, c, is given by c 2 = 1 2 + 1 2 = 1 + 1 = 3 so c = 2. Exact Trigonometric Function Values What angles have an exact expression for their sines, cosines and tangents? You might know that cos(60°)=1/2 and sin(60°)=√3/2 as well as tan(45°)=1, but are 30, 45 and 60 the only angles up to 90° with a formula for their trig values?

tan 30 ° = 1/ √3. cot 60 ° = 1 / tan 60° = 1/ √3. Then, the value of Use sum and difference formulas for cosine. Finding the exact value of the sine, cosine, or tangent of an angle is often easier if we can rewrite the given angle in terms of two angles that have known trigonometric values. Since it is true that the sin of supplementary angles have equal values and the sin function was used to find angle B, you have to check if another triangle may exist with angle A measuring 19 degrees and and angle B measuring 18 degrees.
