Identity VII: (a – b)3 = a3 – b3 – 3ab (a – b) Identity VIII: a3 + b3 + c3 – 3abc = (a + b + c)(a2 + b2 + c2 – ab – bc – ca)

## Why the there is 6 in trigonometry?

Answer. There are only 6 trigonometric ratios because only 6 ratios can define ratios of all sides. For example, If you want ratio between perpendicular and hypotenuse there is sin.
