Prime 8 (No Express) version 2.
Let x shows the perimeter of the circle. If x is the answer to minimize the toral area,

Good solution. But it won't run in Express (no symbolics, no polyroots)
Also "Minimize" (even without a solve block) is a premium function.
But the derivative operator and the "root" function are not and you can use them for a solution in Express. You just have to manually solve a simple equation 😉
Using a more powerful software you may even visualize by creating an animation 😉

But Short and simple.
Attach file please.
Moe is using real Mathcad and this seems to be a Prime only challenge. Nonetheless I would vote for his solution being the winner.
BTW, because Moe's nice compact solution is using Lagrange and the Nabla operator - is the Nabla operator now finally available in Prime 8 or is it still missing?
We could make Moe's solution even a bit more compact by using the symbolic "solve" instead of evaluating the solve block symbolically (which is something not allowed to do in Prime anyway).
It could even be made a one-liner (but I wouldn't suggest doing so):
If the Nabla operator still is not available in Prime, you would have to do it the hard way
As usual Primes infamous auto-labeling bug required to manually re-label some variables to make it work.
I seem to remember to have read that PTC planned to implement a partial derivative operator. While being only an optical display thing it would be appreciated. Is it already implemented in Prime 8 or was I just reading the roadmap for future versions?
Thats disappointing! (I assume the pic is from Prime8 )
And how about the partial derivative operator?
Hi
MATHCAD 15
Converted to Prime 8
I knew that the "grad" operator was available in the original Mathcad, but I haven't seen it in Prime. Yet you show it in the Prime solve block, with a message that it isn't available.
So how did Prime execute the solve block?
It didn't - its lying and cheating
This is what it really does when you ask it to recalculate:
So how did Prime execute the solve block?
The converter simply inserted a picture of the Mathcad 15 region.
Prime did not execute the solve block. As usual for Prime it stores the results of the last calculation within its file and displays them when you open a file. The file is not recalculated automatically when you open a file (as is the case in MC15 with auto-calc on). So the result you see is the result of the last calculation done in MC15 by the converter.
This is also the reason you can use Prime Express as a reader for Prime files which use premium functions. You see what the sheet looked like in full Prime but when you try to recalculate, the premium functions will fail.
So see in ppal's answer that the recalculation in Prime yields just "Find(...)". Actually its an empty solve block without any constraint and as we know Prime won't allow to evaluate a solve block symbolically.
I thought I'd add my 2 cents:
And since a result without an animation is not a solution....
Success!
