I want to compute x__0 as a function of alpha. I tried fsolve but could not make it work (see attached).

What did I do wrong? Are there other ways in Maple to solve such problems?

I am stuck here and would very much appreciate help.

Update:

Its likely that the recently introduced warnings for definite integrals would have helped in this case to find a solution on my own. When I run this worksheet with Maple 2023, it immediately suggests the use of assumptions.

But ODEsteps supports simliar ODEs (see attached).
Is the ODESteps command not generic enough to cover the pendulum or have I missed something?

Imagine you want to precisely refer to this help page

The only way I am aware of is typing the whole string

Task,building,spe……

that it can be pasted as Maple input (with a leading ?) or as search term in the help system.

Are there other methods (like creating a hyperlink by right click somewhere) to extract this information/string once you are in the help system on a specific page?

To create a parametric plot, it seems that all units from an expression have to be removed. Convert, unit_free only removes the outermost unit from an expression. Are there any other commands that could be used?

The attached document describes the problem and solution attempts.

Copying and Pasting of parameters (entered data) or text in text boxes does not work on my MapleSim 2021.1 Windows10 installation.

I tired the usual keys and context menus. Cutting works.

Thats what I get back when I paste text here after cutting

<math xmlns='http://www.w3.org/1998/Math/MathML'></math>

Copy&Paste of components works.  

Is this a known issue?
