The value of lim(x->0)([(100 x)/(sinx)]+...

The value of `lim_(x->0)([(100 x)/(sinx)]+[(99sinx)/x])` (where [.] represents the greatest integral function) is

(a)`199`

(b) ` 198`

(c)` 0`

(d) none of these

Text Solution

Verified by Experts

The correct Answer is:
B
We know that `underset(xto0)lim(sinx)/(x)to1^(-)" and "underset(xto0)lim(x)/(sinx)to1^(+).`
So,`underset(xto0)lim[100(x)/(sinx)]+underset(xto0)lim[99(sinx)/(x)]=100+98=198.`
