Try EXPR("FourCoeff.ChooseInterval()") instead of FourCoeff.ChooseInterval().

yes!
it's ok. The choose box is very elegant also.
Works also with the piecewise function and (with some warnings) also with |sin(t)|
I've now a doubt (I'm aging, hi):
the correct formula for a0 and interval -π..π is divided by PI or by 2*PI? In some books of mine I find one and in others the other form...

And finally we could also include in this program your routine for cx (exponential form coefficient)...
What do you think?
