Solved!

Create a program to use on the solver APP

HP Recommended
HP PRIME

have a question that maybe it was already answered before but I can't find it. if some one could help me on this it will much appreciated.

Let take for exame a program called: Conical_gears that I whan't to use in solver

 

The formula is:

Angle_degrees=ATANG(N1/N2)

 

How can I write this program to use in solver?

I just want to have a list of formulas categorized in memory that I can use in Solver

 

Best regards,

Jorge

For that problem I’ve found a solution and that is declaring the variables in the Solver program.

 

i want to do this:

Thanks for the response, 

 

But what I want to do is:

after selecting the program from the toolbox->User->Conical_gear; 

The expression should be written on the solver evaluation fild, for me to solve it in the order I want.

 

Its more clear now? If I can make this to work I will buy the calculator to use on my classes of mechanical Design (I'm a professor)

Exemple of expression "autofill"Exemple of expression "autofill"

Thanks again !

Hi!, @Jorge_rui :

In APPs, you cann't use the variables nomined with number's subindices or superindices.

You only can use variables with letter's . You can create your own variables, or you can take advantage of the built-in variables in Home view (named A to Z and θ) and in the CAS (named a to z, and a few others).

Kind Regards !.

Hi!, @Jorge_rui :

In the program what i create, you didn't use in Solve. 

Only you needed open the program, with Shift and Program key.

Configure in degress or radians.

Then you can see ... CONIC_GEAR (2KB).

Now, you press "Run" key and see ...

Program Parameters

N1:0

N2:0

Put in each cell, the value what you needed calculate and press "OK" key.

When finalize you see one rectangle with one circle with admiration open symbol in green and white colour and ... CONIC_GEAR ............ (with result value).

Kind Regards !.
Have a nice day !.

Thanks again, and thank you for your patience. 

 

I know now how to run the program you have created, but, that does not let me solve it order to any equation. 

The method I’ve refered on the link is what I need. 

 

I can create an entire app regarding transmission by spur gears and and get a lot of flexibility without all equations over and over,  and in some cases solve to other unknown values, something that Incan do in solver

Hi!, @Jorge_rui :

IMHO, is better work in Engineering calculus use the programming. If you needed obtein other's values in calculus, you can send the equation's and unit's for create the program.

Too can check, for other calculators written by me, ago many years, of Engineering Calculus. See, from ... https://www.hpcalc.org/search.php?query=caporalini

Kind Regards !.
