Determine whether or not exists.
Yes or No?
I think it is yes because the derivative of 0 is just 0 so f'(0) would still exist at 0?
Am i correct or no?
can i ask a quick question about these two problems?
you said sin(1/x) is bounded so therefore it does exist. why is sin(1/x) bounded and sin(5/x) not bounded which therefore does not make sin(5/x) exist?
From looking at the graphs of both they both seem to be bounded.
I guess im just kind of confused on why one exists and the other does not and i have a test coming up this week so im just trying to make sure i understand everything clearly.
Any more help or explanations would be much appreciated.
