How to find continuity of a piecewise function

Continuity is a local property which means that if two functions coincide on the neighbourhood of a point, if one of them is continuous in that point, also the other is. In this case you have a function which is the union of two continuous functions on two intervals whose closures do not intersect.

The Fourier series of f is: a0 + ∞ ∑ n = 1[an ⋅ cos(2nπx L) + bn ⋅ sin(2nπx L)] but we know for obtaining coefficients we have to integrate function from [-T/2,T/2] and intervals are Symmetric but you didn't write that.I have been confused now.

In general when you want to find the derivative of a piece-wise function, you evaluate the two pieces separately, and where they come together, if the function is continuous and the derivative of the left hand side equals the derivative of the right hand side, then you can say that the function is differentiable at that point. i.e. if f(x) f ...1. The problem in your solution is that you're letting n → 1 and the way you wrote f(an) and f(bn) are not exactly right. Instead you should have f(an) = 2 and f(bn) = (1 − 1 n)2 for all n ≥ 1. Now as n → ∞ you get the desired result. Also to your second question, note that proving discontinuity at x = 1 is enough, and in fact that's ...

The same applies to the tangent line. What if the function is not continuous at x=0 -- can you even have a tangent line? Is it possible for a line to touch only one point on a curve when that point is a discontinuity? This is encouraging you to go back and look at your basic understandings of a tangent line as well.1. Yes, your answer is correct. The kink in the graph means the function is not differentiable at 2, but has no bearing on whether it is continuous.
