cosecβ = = 3X and cotβ = 3/X , to find value ( X2 - 1/X2 ) . we know , cosec2β = cot2β +1 putting value , (3X )2 = ( 3/X )2 +1 , OR 9X2 = 9 /X2 + 1 , OR 9X2 – 9/X2 = 1, OR 9( X2 - 1/X2 ) = 1, SO (X2 – 1/X2 ) = 1/9

cosec(^2)l=9x(^2). cot(^2)l=9/(x^2). Use cosec(^2)l-cot(^2)l=1. Then x^2-1/x^2=1/9

Cosec^2x -Cot^2x = 1 (From Formula) From Question, (3x)^2-(3/x)^2=1 3*(x+1/x)*3*(x-1/x)=1 Therefore,(x+1/x) (x-1/x)=1/9 x^2-1/x^2=1/9

cosec^2 I - cot^ l = 1 (3x)^2- (3/x)^2=1 9x^2 - 9/x^2 =1 9(x^2- 1/x^2)=1 x^2-1/x^2 =1/9

From right angle triangle we get (3/x)^2+1=(3x)^2 9x^2-9/(x^2)=1 x^2-1/x^2=1/9
