What is #lim_(xtooo)(sin2x)/x#? Calculus Limits Limits at Infinity and Horizontal Asymptotes 1 Answer 1s2s2p Apr 13, 2018 #0# Explanation: Think of this as: #lim_(xtooo)sin2x*lim_(xtooo)1/x# As #x# tends to #oo#, #1/x# gets smaller and smaller, until it is effectively #0# However, #sin(2x)# can be be anywhere in the range #[-1,1]# at infinity. So, we have: #lim_(xtooo)sin2x*lim_(xtooo)1/x=[0(-1),0(1)]=0# Answer link Related questions What kind of functions have horizontal asymptotes?
