The main tr.nometric iden.ies between tr.nometric functions are proved, using mainly the geometry of the right triangle. For greater and negative angles, .An "iden.y" is a tautology, an equation or statement that is always true, no matter what. For instance, sin x = 1/csc x is an iden.y. To "prove" an iden.y, you have to use logical steps to show that one side of the equation can be transformed into the other side of the equation..Proving Tr.nometric Iden.ies. Proving a tr.nometric iden.y refers to showing that the iden.y is always true, no matter what value of x or is used..Proof of the reciprocal iden.ies. Proof of the tangent and cotangent iden.ies. Proof of the Pythagorean iden.ies..
