I've got a question, how can I add this formula:

dh^4=Dh^4-Dh*Dm^4  ?

I've tried:

Code: [Select]
dh^4=Dh^4-Dh*Dm^4
dh=root(Dh^4-Dh*Dm^4,4)
dh=(Dh^4-Dh*Dm^4)^(1/4)
dh=(Dh^4-Dh*Dm^4)^0.25

What else can I do? It always returns 0...
Testvalues:
Dm=150, Dh=180 --> dh=145

I believe it doesnt work because there are 2 variables with the same lowercase name (on the nspire, the basic variables are lowercase(d) )
Try with different names, to see if it works ?

The syntax of the first line should be good

tried this:
dh=(Dh^4-Dh*Dm^4)^(1/4)
But now it doesn't calculate anything.. nvm, I already know it by now xp

As said Adriweb, dh and Dh are in TI-Basic the same variables (it removes the case). Since FormulaPro uses math.eval() in order to solve part of the problem with CAS, this will leads to a confusing formula you're not looking for.

Try this : dh_=(Dh^4-Dh*Dm^4)^(1/4)

Sorry, i wrote the wrong formula, i read what he said :)

I tried this:
dh=(Dhol^4-Dhol*Dm^4)^(1/4)
and it didn't calculate anything

FP uses the CAS's solve() or nSolve() if not available.... so make sure it works first in the OS ?

I should have made a mistake, I'll look into it, since all the other formulas seem to work (afaict), so it'll be my mistake

Digo assim, quero usar todas as unidades de medidas de todas as coisas em unidades do Sistema Internacional de Unidades.
Por exemplo, nos estados unidos utilizam "ft/pés" e no Brasil(América do Sul) utilizamos "km/h ou m/s".
Não sei como é ae em Portugal, mas aqui utilizamos o Sistema Internacional de Unidades.

Entende?

Quero instalar esse aplicativo e deixar todas as medidas utilizando o Sistema Internacional de Unidades.

Tem algum arquivo específico para deixar todas as unidades no sistema internacional de unidades??

Sou leigo no assunto, não aprendi nem mesmo a instalar ainda.

Obrigado

English:


Say so, I use all units of measure of all things in units of the International System of Units.
For example, in the United States use "ft / ft" and Brazil (South America) use "km / h or m / s."
I do not know how to, and in Portugal, but here we use the International System of Units.

Understand?

I want to install this application and leave all measurements using the International System of Units.

Is there any specific file to make all units in the international system of units?

I am a layman in the subject, not even learned to install yet.

Has any files here. You are ready. With these measures?

He better be careful when doing that, to make sure his results are accurate. I know that some Americans (especially in Texas and New York) tend to be very patriotic and will probably claim that their system of units is the best and the international one, rather than the metric system. :P
