Answer 3

@ganeshie8 - :/

Answer 4

the floor function is pulling the 0.9999999 to 0

Answer 5

0.999 ??????????? how come u got this value

Answer 6

@ganeshie8 -bhai sahi sai samjh mai nahai aaya :'(

Answer 7

when you take right hand limit, \(\sin x / x \) approaches to 1 as x approaches 0. it never equals 1. So when u take floor value of 0.99999 you wud get 0

Answer 8

oh :OOO

Answer 9

same applies for the left hand limit also

Answer 10

oh ::O

Answer 11

floor(-0.9999999) = -1

Answer 12

@ganeshie8
floor(-0.9999999) = -1
it shpuld be 0 lol
0.99 is biiger than 0
so 0+
[-o+]= -0=0
XD

Answer 13

dint get u

Answer 14

wait see lim x-->0- [sin(-1)/-1]
lim x->0- [sim1]
sin 1 = 0.84 which is o+ (sligltly bigger than 0]
as u know if the inner part of [] is greater than n then the naswer will be n if leser than n (n-) than answer is n-1 XD
