I am returning to school, adult ed kind of thing, to learn about
electronics. For the tests, I need a calculator which can solve
systems of linear equations with complex coefficients. (When doing
the homework at home, I use Mathcad.)
I just went to Radio Shack, and got a case of sticker shock (much like
what I'm feeling these days when I go to buy gasoline for my car). The
cheap calculators, which cannot do systems of linear equations, cost
around $20. The calculators which look like they probably can do
systems of linear equations -- although it's not entirely clear from
the packaging -- jump to around $125 to $150. Prices on E-bay are
cheaper, but I'm not entirely sure what I am buying.
Can someone suggest a few models of calculators that:
1. Can solve systems of linear equations with complex coefficients.
2. Are relatively easy to learn to use, and to do the data entry.
3. If possible, perhaps cost less than $100, though I will spend
$100+ if it's unavoidable.
4. Does other stuff that is like to come up in undergrad level EE
courses and tests.
If anyone really wants to be a Saint, take a peek on E-bay, at some of
the stuff currently on sale, and tell me if any of those calculators
would meet my requirements. (Here's a list of just a few that are
currently being offered under the keywords "Calculator" and
"Scientific": TI-81, TI-83, TI-85, TI-89.)
A check of the TI Web site suggests that the TI-83 or TI-84 have the
features I want, but again, it's hard to know without having used
them. At the high end, they have the Voyager 200 (which costs $200),
and the TI-89 Titanium (which costs $150). Recommendations for the
minimum I really need for my purposes -- and for options for brands
other than TI -- would be appreciated.
Thanks in advance for all replies.
