Question

prove that (1 + cos theta + sin theta/ 1 + cos theta - sin theta)² = 1 + sin theta/ 1 - sin theta​

Answer 1

Answer:

Step-by-step explanation:

            we know that 1+cosФ =2sin^2 Ф/2

                                     sinФ=2sinФ/2 cosФ/2

                       put in the expression,

                          we get (sinФ/2 +cosФ/2)² in numerator

                  and (sinФ/2 -cosФ/2)² in denominator

                      simplify through (a+b)² = a²+b²+2ab

                                          (a-b)² = a²+b²-2ab formula u will get that

                         let me know if u got this
