## Symbolic solution by using "Find" in Mathcad Prime 2.0

Symbolic solution of system of equations by using a keyword "Find" doesn't work correctly in Mathcad Prime 2.0 F000 (see example in the attachment). But in Mathcad 15 M010 all works fine. Another bug ?

Symbolic find has not yet been implemented in Mathcad Prime. We implemented nearly all of symbolics, but this feature did not fit in the scheduled for Mathcad Prime 2.0.

When you convert a worksheet from Mathcad 15 or earlier, then open the file, you see the saved results. Once you recalculate, the results update to the Mathcad Prime results.

strangely, from a conversion it will work, but it is very fragile.

Yes. The answer is lost after recalculating the worksheet.

We needed Find()-> only in Mathcad 5 (6?) with menu comands of symbolic math but without symbolics commands. For symbolic solution of sysmems of alg.equations.

Now we can use the Solve command in Mathcad 15 and Prime!

Hello everyone, I'm new to mathcad and Im using the prime 3 version. Reading this and looking for in internet I haven´t been able to find how to solve system of equations with end value condition.

What I'm trying to do is to solve g ' ' (x):=M with M:=P2*x-P3 for g ' (x=0) := 0, g ' (x=L) := 0, g (x=0) := 1, and g (x=L) := 0.

I already tried with solve block and with replace like doing it step by step almost by hand but, is there an eassier way?

I attach a sheet with averything I have tried

thanks.
