    Differentiation problem

    use quotient rule. where u=x v=sqrt (x squared + 1) u'=1 v'=x/sqrt(x squared+1) so dy/dx= [sqrt(x squared + 1)-x^2/sqrt(x squared+1)]/(x squared+1) thats pretty messy. dy/dx=1/sqrt (x squared + 1) - x^2/(x^2+1)^(3/2) i think edit:dy/dx=(x^2+1)/((x^2+1)^(3/2) - x^2/(x^2+1)^(3/2) =1 /...
