Re: how-to with TI86 please?
if you are working with polynomials, use [2nd] [poly] gives you every
single root there is, including double roots, and including complex
roots. it's an eyeblink for 2nd and 3rd orders, and it takes a while
on 10th orders, but, heck, if you do that by hand it would take you a
year :-).
If it isn't a polynomial, and you are sure it has just one root, use
the solver. or, if you only need one root, use the solver.
If it's none of the above, graph it, and use >|Math|root. now move
your cursor towards the root you are interested in with the cursor
keys, and hit enter. the thing newtonmethods it's way to the nearest
root. the closer you are, the faster it'll fly.
NB: There are some specific points between the attraction basin
boundaries (usually found right in the middle of roots) that display
chaotic behavior.
NB2: the More, math,root, method doesn't find you any complex.
