What version are you using? I'm guessing something fairly old. This
doesn't happen in 5.10 and later.
Anyway, if it's an old version, maxima already has a function named
I1, so maxima converts your i1 to I1 because the symbol already
exists. (I1 was the modified Bessel function of the first order.
This no longer exists; it's called bessel_i now.)
