multiply top and bottom by sqrt(x+1)

you should get -(x-3)/[(x-3)sqrt(x+1)] - Sep 21st 2009, 02:15 PMArturo_026

yes multiply top and bottom by 2 +sqrt(x+1)

then you get -1/[2+sqrt(x+1)]

and lim -1/[2+sqrt(x+1)] = -1/3 not 0

x->0 - Sep 21st 2009, 02:28 PMArturo_026
Oh, I see where my error was, how embarrasing.

Thanks so much
