In addition to names, parameter types also need to be converted. They need to be supported in both directions. As for trigonometric functions, the SMath tries to automatically work with names, which prevents them from being supported in the plugin in a controlled way.

Hi Viacheslav. Forgetting about types for a moment, if you add a line with "alias(arg=argument, asin=arcsin, ... )" and some other aliases to the plugin's "in.tmp" file, wouldn't it do the conversion automatically?





Best regards.
Alvaro.

You can check it yourself. The plugin supports including custom commands using the "with.inc" file. The file content is added automatically with each conversion to the in.tmp file header.

Hi Viacheslav. This is the modified with.inc:


And this is the test:

I use u=Heaviside because there is a plugin with this function, useless for integration, but there must be some other better name. Also, there are some other functions, like GAMMA, Bessel, Airy, etc.

Since the maple plugin is used as an intermediary, all interpreters based on it will be located here.

In the future, a separate plugin can be made to remove unnecessary transformations.

The python.exe interpreter must be accessible via known paths.

How can we to put correct view - as in the Maple-picture?

Hi Valery. I don't know from which version of Maple has implicit plot 3D, but I'm sure version 6 doesn't have it. You can try pMesh or pSurf.

Oh, I see. Maple 6 have that function. I also had no idea that you could use setprop with maple plots. I guess then that what you need is to find the right projection. It's difficult since it's not interactive. Maybe this helps.

Hi. Some improvements, I guess. You can sterilize the units inside a wrapper function. Also, using scaling=constrained looks with the real proportions.

Can you solve this problem? The submarine's cross-section is an ellipse, and the bow and stern are halves of the ellipsoid.
Слабо?

Hi Valery. And what's the problem? It has a curious shape, but I suppose it's not one of the strangest I've seen. I don't know what problem you're trying to solve. I thought it was just about getting the graph like in Mathcad.

Best regards.

Thanks Alvaro for the interest.

V, S, L=constants, a, b -?
By symbolic and/or numeric math. With 3D-plot with animation!

Hy Valery. Assuming the cameraman was very skilled and there's no roll angle, and disregarding perspective effects, you can try adjusting the values ​​for a setup similar to the following

How to calculate the length of an ellipse and the area of an ellipsoid?

As it is not a political question, you may rely on Wikipedia: https://en.wikipedia.org/wiki/Ellipsoid

Maxima can be replaced by Gnu Scientific Library plugin.

Edit: Alvaro found a typo and suggested to use the definition of the elliptic integrals directly.

The (possibly) elliptical outer hull of the submarine doesn't carry pressure loads. The cross section of the actual internal pressure vessel seems to consist of two circle segments. Elliptical sections would easily collapse under external pressure. Circular sections are bending-free and the internal and external bulkheads and stringers just prevent the hull from buckling due to compressive membrane stress. The outer hull may contribute to that in the sense of a sandwich design. Of course, there might be non-uniform pressure loads due to nearby detonations or collisions with the ground or other vessels.
