log(value,base) versus logb(value,base)

[Han]

In the CAS environment, objects separated by commas are elements of a list. Thus command(a,b,c,d) is actually interpreted as command([a,b,c,d]) where [] is a list (in the CAS environment). Secondly, LOG() and log() are different commands. You are probably trying to evaluate LOG(e,i), which is \( \log_i(e) \). However, if you type log(e,i) in the CAS environment then this is equivalent to LN({e,i}) in the Home environment since the CAS implements ln(x) as log(x) -- most CAS do this as well.

That said, when I type in log(e,i) in the CAS view, I get \( [1 \quad \frac{i}{2}*\pi ] \) and not the reverse-ordered list that you typed.
