The manuals provided with the 49G are useless, and the advanced user's guide (while a valiant attempt) falls well short of the in-depth discussion on using this great new tool to its limits.
I finally ditched my TI-86 after years as a loyal TI fan -- but this transition (as worthwhile an effort as it is) will absolutely kill me if I can't find a good reference text to help me hone my skills with the graphing, statistic, calculus and other functions.
For those of you who have both a 48 and a 49 -- would one or all of the 48GX manuals help me get a grip on the 49? If so, which one(s)???
Thanks!
P.S. - Anybody have problems graphing fractional exponents on the 49? (negative x values won't plot, but re-writing the equation with a radical in the denominator works fine...?) -- does the 48 have this problem?
