A82: Accessing and changing stuff around in the VAT
Hi guys. I haven't been doing any programming in a long time, since my
de-bugging of Blockbuster a couple of months ago. I've been thinking
that I'd like to do a math program -- symbolic differentiation. I would
like for the person to first enter the equation into Y=, and then the
program prompts them which equation they want to differentiate (Y1, Y2,
etc.), finds the contents of the equation, differentiates it, and spits
it back out, possibly writing the derivitive in another equation
variable, so they can graph it and everything.
Now, my question is, how would I go about accessing the contents of Y1
or any of the other equation variables? And then, how would I write a
new equation into the VAT?
Thanks
Doug Torrance
