Re: TI-85 vs. TI-82
[Prev][Next][Index][Thread]
Yes, but a table does make limits easier, you can see the values approach
the limit. Also, solver is way too slow...
Also, notice I said *direct* function evaluation. You don't need to store x
for each entry, you can type y1(5), y1(0), etc. Saves several keystrokes
each time... I never said it was impossible on the 85, I said it was more
difficult...
