A triangle is divided into six parts, 3-sides and 3-angles so to determine the relationship between sides and angles we need to study trigonometry. The first known table of chords was produced by the Greek mathematician Hipparchus in about 140 BC. When we want to calculate the function for an angle larger than a full rotation of 360 (2 radians) we subtract as many full rotations as needed to bring it back below 360 (2 radians): 370 is greater than 360 so let us subtract 360, cos(370) = cos(10) = 0.985 (to 3 decimal places). Triangle with sides a,b,c and respectively opposite angles A,B,C.
