Hello
I'am a little confused. In my textbook it is written that all odd function can be described by a sine series.
I have this following equation from an exercise:
A_{0}+\sum\limits_{n=1}^\infty (A_{n} cos(n \phi) + B_{n} sin(n \phi))c^{n} = sin(\dfrac{\phi}{2})
It's a standard...
Hello.
If I have this equation:
And this general solution:
Would it then be wrong to write the above solution with only positive values of n? In my textbook they often write the result from a superposition with only positive values of n, becasue the negative values of n already...
