comment Comb Function — First Derivative at a Point
As far as I can tell, the function at hand is defined on the domain of all real integer numbers. Also, there is no limiting process characteristic for a derivative of a continuous function.

comment Is the following substitution legitimate?
Emmad, I quess your reply also answers my question about the seeming similarity with boundary value problems in differential equations. In the boundary value problems the equalities given as boundary conditions are absolute, unlike the case at hand, right?

Thanks, Emmad to you too.

Ted, but the first equation shows that $b_1$ depends on $x$, doesn't it? Therefore, Deven's reply holds.

Thanks a bunch, Deven. This appeared to be something akin to the boundary value problems in differential equations. How would you comment the seeming similarity of the above incorrect substitution to the boundary value problems?
