Homework Statement
[/B]
We have a function f(x) = |cos(x)|.
It's written that it is piecewise continuous in its domain.
I see that it's not "smooth" function, but why it is not continuous function - from the definition is should be..
Homework Equations
[/B]
We say that a function f is continuous at an interior point c of its domain if
lim(x->c) f(x) = f(c).
The Attempt at a Solution

I solved the problem but this piecewise continuity is bothering me
