Well, I finally went out and bit the bullet. I purchased the TI-89
Titanium. I have to say that for the price I paid, I'm not wildly
impressed. The display is not at all vivid or strong, and the
keyboard is anything but intuitive.
However, I'm posting/griping about a particular issue. The calculator
comes with a particular program, a Simultaeneous equation solver,
which is precisely what I purchased it for. It's actually a pretty
good program, in terms of data entry, but it has one major
idiosyncracy (at least that I've found so far): When I put in
equations with complex coefficients, as often as not it reports
results with complex values in the denominators, along the lines of:
..345/(1.34 + 2.3j)
Sometimes the solution is even more complicated, in the form of
(a + bi)/(c+di)
It seems a no brainer to me that the calculator should automatically
do the work of clearing the complex value from the denominator, giving
me a nice, simple
1.234 + 5.678j
Does anyone know if there is a simple, one-button way to tell the
program to flush the complex numbers from the denominator, to give me
the simple result that I need?
Thanks in advance for all replies.
