Looks straight forward to me. For all x larger than 1 but less than 2, [x]= 1 so the limit, as x approaches 2find

lim (-1)^[x]

x->2

[x] is the greatest integer function

-> means tends to

thanks to any help.

For x larger than 2 but less than 3, [x]= 2. So what is the limit as x approaches 2 from the above? And what does that tell you about the limit itself?

Looks to me that the limit does not exist.find

lim (-1)^[x]

x->2

[x] is the greatest integer function

-> means tends to

thanks to any help.

There are different answers for the +ve and -ve limit.

After a week, I would suspect that the OP just can't be bothered to look at the responses and see nothing wrong with posting the answer- in case someone else is interested.
