#lim_(x->oo)(x-1)/(2x+cos(x))=# ? Calculus Limits Determining Limits Algebraically 1 Answer Cesareo R. Dec 9, 2016 #1/2# Explanation: #(x-1)/(2x+cos(x))=x/x(1-1/x)/(2+cos(x)/x) = (1-1/x)/(2+cos(x)/x)# #lim_(x->oo)(x-1)/(2x+cos(x))=(lim_(x->oo)(1-1/x))/(lim_(x->oo)(2+cos(x)/x)) = 1/2# Note that #abs(cos(x)) le 1# Answer link Related questions How do you find the limit #lim_(x->5)(x^2-6x+5)/(x^2-25)# ?
