If `{x}` denotes the fractional part of x, then `lim_(xrarr1) (x sin {x})/(x-1)`, is

Answer» Correct Answer - C
We,
` lim_(xto1^-)(xsin{x})/(x-1)=lim_(xto1)(xsinx)/(x-1)to-oo`
and
` lim_(xto1^+)(sin{x})/(x-1)=lim_(xto1^-) ((x sin x-1))/(x-1)=1xx1=1`
Clearly , `lim_(xto1^-)(xsin{x})/(x-1) ne lim_(xto1^-)(xsin{x})/(x-1)`
So `lim_(xto1^-)(xsin{x})/(x-1)` does not exist.
