CAS fourier_an ...
Hello friends,

I try to use the new Funktion "fourier_an", "..._bn" or "..._cn" on CAS.
The function I try to approximate is a rectangle signal.

T=10ms
f(x)= 10V = û
a=0
n=1...6

In CAS: fourier_bn(Expr,Var,T,n,a)
so I type fourier_bn(10,x,10,1,0) for b1

Normally the result is:
b1=û*2/PI=20/PI
b2=0
b3=û*2/(3*PI)=20/(3*PI)
b4=0
b5=û*2/(5*PI)=20/(5*PI)
b6=0
a0=û/2=5

But with HP Prime calculator:
b1=b2=b3=b4=b5=b6=0
a0=10
The results are compleately wrong!!!

Is there a mistake in using the function on my side or is it an bug?

Thank you in advance for your help.
