Aug 17, 2001 · 2x+1−x2 =2which can be solved by factoring. That is what we will do here. First, subtract 2 from both sides of the above equation and then multiply through by (−1) to obtain sin2 t−2sint+1=0: Factoring this expression yields (sint−1)2 =0: The only solution to this last expression is given by sint =1or t = ˇ 2 +2kˇ where k is any integer.

1. Introduction An identity is an equality relationship between two mathematical expressions. For example, in basic algebra students are expected to master various algbriac factoring identities such as a 2−b =(a−b)(a+b)or a 3+b =(a+b)(a2 −ab+b2): Identities such as these are used to simplifly algebriac expressions and to solve alge-briac ...
