Question

Prove that (sin theta + cosec theta)² + ( cos theta + sec theta)² - (tan² theta + cot² theta) = 7​

Answer 1

sin o+ casee o) +(cas o+ yee O)3 = 7+ tan'0 + cot? O sin O+ 2 sinoLosec o +osec 0 + cos"0 +2 cososie0 +se0 %3D = 1 + losec o +dec ?0 +2+2 sin? 0+ cas O = 1) =1+2+1+ cot?0+ 1+ tan 0+2 L01ee 0 = 1+cat?0 7+ lot0 + tan?0 %3D LHS = RHS Hence, browed
