`lim_(xtooo) x sin"" 1/x` का मान ज्ञात कीजिये।

Answer» `underset(xtooo)lim x sin ""1/x=underset(x to oo)lim (sin (1//2))/(1//x)`
माना `1/x=theta` अतः यदि `x=oo` तब `theta=0`
`therefore x to ooimpliestheta to 0`
`therefore underset(xtooo)lim (sin 1//x)/((1//x))=underset(xto0)lim(sin theta)/(theta)=1`
