The limit x tends to zero ([100x/sinx] +[99sinx/x]) is 198 where [.] is greatest integer function.

  • When x tends to 0 x is less than sinx, that is x < sinx
  • Hence \frac{x}{sinx} < 1 and \frac{sinx}{x} > 1.
  • Hence 100\frac{x}{sinx}  &lt; 100 and 99\frac{sinx}{x} &gt; 99
  • now applying the greatest integer function on the first one we get ,[100x/sinx] = 99 ( As it is strictly less than 100)
  • Again applying the greatest integer function on the second one we get, [99sinx/x] = 99 ( As it is strictly greater than 99)
  • Hence  limit x tends to zero ([100x/sinx] +[99sinx/x]) = 99 + 99 = 198, where [.] is greatest integer function.
  • So the required limit is 198.
