Have you never plotted the curve y = Tan(x)?


Hmm, I guess I don't understand the word continuous then.

The characteristic which I'm talking about isn't common to y = tan x though.

I think your angling after discontinious at every point (in R-).

If a function is continuous everywhere, then for each point c, Limx->c-f(x) = Limx->c+f(x). I.e, the limit is the same if you take it from the left or from the right.

That's true, but not quite the definition of continuity.

Those limits need to exist and both equal f(c).

I did say "if it's continuous, then...". :wink:
