Answer:
cosec2A +2
Step-by-step explanation:
LHS=(sin^2 A/ cos^2A) + (cos^A+ sin^2A)+2
LHS=(sin^2 A/ cos^2A) + (cos^A+ sin^2A)+2=(sin^4A + cos^4A)/sin^2A.cos^2A)+ 2
LHS=(sin^2 A/ cos^2A) + (cos^A+ sin^2A)+2=(sin^4A + cos^4A)/sin^2A.cos^2A)+ 2=(1/sin2A) +2
LHS=(sin^2 A/ cos^2A) + (cos^A+ sin^2A)+2=(sin^4A + cos^4A)/sin^2A.cos^2A)+ 2=(1/sin2A) +2=cosec2A+ 2 Ans
