Question
(sin+cos)^2/(1+2sin cos)

Answer
((sinA + cosA)^2)/(1 + ((2sinA)(cosA)))

((sinA + cosA)(sinA + cosA))/(1 + 2sinAcosA)

(sinA^2 + sinAcosA + sinAcosA + cosA^2)/(1 + 2sinAcosA)

(sinA^2 + 2sinAcosA + cosA^2)/(1 + 2sinAcosA)

(sinA^2 + cosA^2 + 2sinAcosA)/(1 + 2sinAcosA)

sinA^2 + cosA^2 = 1

so

(1 + 2sinAcosA)/(1 + 2sinAcosA)

ANS : 1
