## How to connect to additional frames of m...

When defining 2 frames as shown here

only one additional port is shown in the workspace. Mouse over indictes an array of 2 ports.

I could not find any examples or explanations how to connect to an array of frames.

Can someone connect two ridig body frames to it?

## How to show equality of expressions with...

Maple

I am searching for high level commands or techniques to show equality of expressions containing square roots that can be complex as here

In an ideal world is() with the right assumptions should show equality. However, in the attached example, I failed already with my manual skills.

What did I miss here?

Maple

I was searching for an “uneval” command that returns an expression unevaluated (as Maple returns an output). In the attached example I am using eval which works in this instance since the integral is entered in an inert form.

 (2)

Since the use of eval to obtain something unevaluated is somehow confusing (and might not work in all instances): Is there a better way than to use eval?

Maple

I am looking for something like the equal sign (“=”) with a question mark (“?”) on top.

This would be handy to express an unknown relation or something that has to be proofed.

If not: Is it possible to create custom symbols?

Maple

I made this observation when comapring two expression containg elliptic integrals (see attached)

Such unevaluated complex output maybe be the reason why fsolve and plot sometimes did not produce output on similar expressions in another question I posted
