Establish the following identity. 1- cos e sec 0-1 1+ cos 0 sec 0+1 sec 0-1 To establish the identity, start with the side containing the more complicated expression. Since both sides have simple expressions, start with either of the expressions. Here, start with sec 0+1 sec 0-1 sec 0+ 1. +1 Multiply the numerator and the denominator of the expression by a suitable factor in such a way that the fractions are removed from the numerator and the denominator. Multiply by a well-chosen 1. 1 + 1- cos e 1+ cos 0
