Question

If R=lim_(x rarr0^(+))f(x) then the value of cos(100R) is​

Answer 1

Answer:

Correct option is

B

198

From the graph of x and sin x, we know that for all x > 0,

x>sinx or

sinx

x

>1

Therefore,

x

sinx

<1

Thus, 100<

sinx

100x

<101

And , 98<

x

99sinx

<99

Thus, [

sinx

100x

]=100

And, [

x

99sinx

]=98

Hence, their sum is 100+98=198
