limit Help

is it possible to find a bounded function g:(0,10) to R that has a left-hand limit but not the right- hand limit

Re: limit Help

hi Doraemonlover

Welcome to the forum. 

How about g(x) = tan(pi.x/20)  ?

Oh no!  You wanted 'bounded'.

Thinking ....................................

Version 2.

g(x) = 5sin(1/(10-x))

The function oscillates more and more wildly as x approaches 10 so has no limit.
