How do you find #lim (1-t/(t-1))/(1-sqrtt/(t-1))# as #t->oo# using l'Hospital's Rule? Calculus Tests of Convergence / Divergence Indeterminate Forms and de L'hospital's Rule 1 Answer Cesareo R. Dec 4, 2017 #0# Explanation: # (1-t/(t-1))/(1-sqrtt/(t-1)) = -1/(t-1-sqrtt) =-1/sqrtt(1/(sqrt t-1/sqrtt-1))# then #lim_(t->oo)(1-t/(t-1))/(1-sqrtt/(t-1)) = lim_(t->oo)-1/sqrtt(1/(sqrt t-1/sqrtt-1)) = 0# Answer link Related questions What is L'hospital's Rule?
