1. The problem statement, all variables and given/known data Find limit of sin(x).sin^-1(x)/x^2 as x approaches 0 2. Relevant equations Maybe L'Hopital's rule. 3. The attempt at a solution First, i put in zero, and got the indeterminate form 0/0 So, i used L'Hopital's rule and got this: [cosx.sin^-1(x) + sinx.-sin^-2(x).cosx]/2x And again when putting zero, i get [1/0 + 0]/0 = infinity/0 So i tried to differentiate again, but it's become so big, i don't know what's what in my copybook. Help!
