1/(cosecA--cotA) --1/sinA =1/sinA -- 1/(cosecA+cotA)

1.	1/(cosecA--cotA) --1/sinA =1/sinA -- 1/(cosecA+cotA)
Answer» For this question you have to change the location of LHS and RHS..... LHS:= 1/(CosecA-CotA) - 1/(cosecA+CotA) =CosecA+CotA+CosecA-CotA/Cosec^2A - Cot^2A=2cosecARHS:=1/sinA + 1/sinA=2/sinA=2CosecAProved!!!! 1
