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? The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios (also called trigonometric functions) such as sine. Details. The underlying functions newsine and newcosine work by breaking a given angle down into multiples of 90, 30, 15, 3, and 1 degree(s). The values at 3 degrees were found using combinations of 15 and 72 degrees, and the values at 1 degree by using the sine and cosine triple angle formulas and solving the resultant cubics.

The result can be shown in multiple forms. Exact Form: √2 2 + 1 2 2 2 + 1 2.

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. Supplementary angles are angles who's sum equate to 180 degrees.
