If the value of my answer when I compute the limit of a function as it tends to c is 0. Not infinity. Is it then continuous?
That is the limit as $x$ tends to $90$ in the function $f(x) = \cos (x)$
The answer of the above is 0, is the function continuous at 90? Thanks
Edit: Please determine the continuity or otherwise of $$f(x) = \frac{x-36}{\sqrt x - 36}$$ at the point x = 36.
