Math and Science / Re: Calculus with Velocities and other stuff

I think the problem may be in your first integral, but I'm not sure where. Try plugging in the values from it back to the original equations and see if thats working

My guess is you'd have it check hashes or something like that every once in a while

But shouldn't there be something done to the X in the exponent?
why? your integrating relative to dy not x. assuming x and y are independent then there should be nothing done to the x

then you have a constant your integrating(relative to changes in y) so you have 1/2V(y)^2=y*(C(y)*e^(2*x*C(x))+g)

abs(V(x))^2 is the same as V(x)^2
Ok just how you wrote it up its not obvious thats your reasoning. It just says
e^(x*C(x)) = abs(V(x))

good so far, right?

I sub in e^(x*C(x)) for V(x) in the next equation
Is C(y) and C(x) constants or are they functions that can have different outputs depending on the x and y?

V(x) is squared... Did I not put that in?
You did just I'm not paying attention.

One other note is that you go from abs(V(x)) to V(x). I'm not sure if that would be considered a safe assumption

why do you go from V(x) to dx^2/dt^2 shouldn't it be dx/dt instead?

yeah but it might be an interesting thing to get if it was cheap enough.

Probably since all the resources linked were on the chinese part of TI's website and he said it was hosted by TI-China

Nice find. What would that be in dollars?

We want a good relationship with TI so that they do not try to stop us from doing what we want.
Protip: for years, before the PTTKillers, modifying the boot1 and nLaunch, they've always been trying to stop us from exercising our user rights on the hardware we own ;)

We don't want a 3.3 that blocks downgrade and native code.
It undoubtedly will, and would have even without the PTTKillers, modifying the boot1 and nLaunch - all of which were released after OS 3.2.0.1212, which blocked access to native code again.
They didn't block downgrade, though that may have been them trying to cover themselves in case they messed up and had lots of bugs. There's no point in antagonizing TI anyways. They may try to be nice to us one day.

Its useful being able to see all the new posts though. At least it is for me.
Maybe there could be a forum games section?

I thought it was already known that it had a z80?
I remember people were already running test programs on it to find out about it.
DJ_0 I'd think the main thing for making old asm programs run on the 84C would be to patch the display routines and maybe some of the variable access and stuff. Just find where things have changed and see if there is a reasonable way to patch that.
