Hllo Lakshmi!

Since in your qstn x is tending to reach minus infinity,

the answer will be infinity.
Explaination: 
sin(1/x) range is betwn [-1,1] thus whatever ould be the limit it will give some finite value between -1 to 1.
Now if U think about x exponentials,
then degree/power in numerator is greater than in denominator.
and hence in such cases the the nswer is infinite.
hence even power is associated with numerator.
