Mertens Function Error
I am new to Sage, so I suppose the answer to this is ridiculously obvious, but please go easy on me!
I have an error when I try to get Mertens function as an output yet: I know the summation works for other functions; and I know the Moebius function is defined on the range. So what's going on?
This is the input and output:
sage: var('j') sage: f = moebius(j) TypeError Traceback (most recent call last) .... ----> f=moebius(j) ... TypeError: 'sage.symbolic.expression.Expression' object is not iterable
