Can a TI-86 do this?
Please excuse my ignorance, but I have never owned a graphical
calculator before. I am very interested in the TI-86. I have two
possible justifications for an expensive calculator.
1) The ability to plot a 9th order polynomial equation used to
linearize a thermalcouple signal. It would be handy to see what
temperatures are in the "bumpy zone."
2) Calculating the values of two resistors and a capcitor needed to
set the frequency of a 555 IC.
I would need to enter a look-up table of the common values of
resistors and capacitors. Those values would then be fed into the
equation f=1.44/(Ra+Rb)C. A table or graph should be produced in
which a frequency could be looked up and the values need for that
frequency would be displayed. The following tabel would be an
example, but with over one hundred possibilities:
Freq Ra Rb C
x x x x
x x x x
x x x x
x x x x
x x x x
Any advice would be appreciated
Thanks,
