TI-86 Calculator capabilities
Hello,
Q1.
When I graph 2 linear functions, each
having a slope that is the negative
reciprocal of the other, I end up with
2 lines that ARE NOT perpendicular to each
other...I tried adjusting the scale of the
x and y coordinates in the WINDOW screen
without success( wouldn't a 1 to 1 scale
between x & y work?). What's up???
Q2.
Is there a way to program the calculator
to take a 3rd derivative, 4th derivative
...etc.???? And without writing a 50k
program!!!
At present, the only way I can
check my Calculus problems involving
'greater-than' double derivatives("der2"),
requires that I compare the calculators
first derivative on the original
expression at 'x' with my manually derived
1st derivative at 'x'...and simply repeat
this process for deeper and deeper
derivatives.
Thanks...
