Good day. How to find a formula to determine automatically? Also how do you replace values and combine all formulas into one automatically?

How to find a formula to determine automatically?
You mean: solve for λ

Hi. Try this too. Needs a "Nightly builds":
.
I meant. Is it possible to automatically convert a formula to find a value from it? Type as in the example in the picture
isol2.sm
Best regards.
Alvaro.

Hi Вуаутвук. Do you have the "Nightly builds"? (Download it at the link). I use a very recent new behavior, not pressent in the stable beta versions).
Best regards.
Alvaro.

I have the latest version.
Ok. Do you evaluate symbolically d?
Best regards.
Alvaro.

I have the latest version.
I want to convert the formula from P = to formula D =. In symbolic form.

I have the latest version.
I'm understood, thank you.

I didn't quite understand what it was, but thank you.

Read like this:
1. 'f' is an expression, i.e: a formula
2. it depends upon 10 parameters from blue sky
3. you wanted its result be 'P' call it "unk" [unknown]
4. if you can measure then assign 9 parameters,
there is one left not measured then "unk'
5. you said you wanted to solve for 'd',
given all 9 other parameters and the result "unk"
solving for 'd' is the maple implicit solve block
maple(solve(unk-f,d)) ... evaluate symbolic.
6. symbolic expresses 'd' wrt all 9 given parameters
and the demanded "unk"
implicit unk-f means unk-f=0

I can not do it

I can not do it
Please: attach the Smath document.
Once patients are doctored => recycled !

Here is doctored in pink [2 regions].
Your original SS 7251 opened/doctored in my SS 6179
returned SS 6179. If you don't see the graph, please let me know.
In that case, I will make a snippet.

Hi Вуаутвук. Some notes:
- Use units. For instance, alpha=45 isn't usual, but alpha=45*deg is.
- R.max^3-R.min^3 is more usual than R.min^3-R.max^3.
- You can't solve P with the same equation from "f".
- Empirical coeffs usually carry some units.
I don't know very well the process that you're describing, but guess that this is a good aprox to the correct solution.
