How do you create a variable name with a dot?  ie/ ini.param

I don't think it's possible without using single quotes ie `ini.param`.  The single quotes will always need to be used.

Not sure why I need to invoke the simplify command here, shouldn't the immediate simplification occur?

simplify(%)
                   

However, it does work algebraically

There is a simulation of a T handle in space done in matlab https://rotations.berkeley.edu/a-tumbling-t-handle-in-space/

Would like to see someone do this in Maple. More specifically how the Matlab code would look like translated to Maple

Can we change the color of the units measure?

ie 5 m (5 meters - where m is default black) can the m be changed to a different color for all unit measure entries?

Two questions. 

1/ Can we modify the output look of the Quiz question?  (ie change the size of the table that is created - make it smaller?)

2/ How to make an algorithmic question ie. for adding two different numbers using the Quiz command?  What I mean here is to randomly change the numbers each time.

I was trying something like

Quiz("What is ", a+b, proc () local a, b: a := rand(1 .. 20)(): b := rand(1 .. 20)(): end)

But the values don't get passed to a and b so the answer will only be a+b.  Any way to get values passed to the variables?
