Hello everybody , I am New with Ti CX CAS and need help.
First , I have a basic equation as: Re = ( ρ * v * d ) / μ .
I find the Re value but I wish I could find any of the variables I already have the case Re .
How could I perform this function ?
Example : Re = ( ρ * v * d ) / μ
Rc = 2; ρ = 1; d = 5, v = μ = 0.5 ?.
How to find the v =

According if someone can give me a place to have a program booklet for the calculator .

How to find the v =
Rearranging the equation gives this

v = (Re * u) / (p * d)

I am not sure if the calculator does this

You can also replace v by x and graph both the formulas
Y1 = Re
Y2 = ( ρ * X * d ) / μ
and then intersect them

Hi and welcome to CodeWalrus. To answer this question, generally booklets are rarely available alone in physical format, but you can download most of them on TI website at https://education.ti.com/en/us/downloads-and-activities?active=guidebooks . :)

OK thank you.
Changing the equation and rearranging know do. But what I want is a single equation to find any of the missing variables.

I would like to know how to program it. :thumbsup:

You need to start learning programming from scratch.....
