No the limiti is #0#, because when #xrarroo#, #1/xrarr0# and so #sin0=0#.

These are limits they don't exist:

#lim_(xrarr+oo)sinx#

or

#lim_(xrarr0)sin(1/x)#.

(#sinoo# does not exist).

If someone told you the limit does not exist for that reason, they've probably confused this question

#lim_(xrarroo) sin (1/x)# which is #0#

With this one

#lim_(xrarr0) sin (1/x)# which down not exist because the values cover #[-1, 1]# over shorter and shorter intervals as #xrarr0#

Actually, that WOULD be correct if you were finding the limit of #sin(x)#. As #x# approaches infinity, #sin(1/x)# just becomes #sin(0)#, which is #0#. graph{sin(1/x) [-9.775, 10.225, -4.78, 5.22]}
