Suppose that we have something like

plots:-animate(F,[theta],theta=0..2*Pi,background=plot([cos(t)-2,sin(t),t=0..2*Pi]),
scaling=constrained,axes=none);

I want to change the range of the parameter theta to something like theta=L[i],i=1..20.
Here, L is a list of numbers. Can I?
Thank you.

I came across this example from Maple's Online Help:

F := proc(t)
plottools[line]([-2,0], [cos(t)-2, sin(t)], color=blue),
plottools[line]([cos(t)-2, sin(t)], [t, sin(t)], color=blue),
plot(sin(x), x=0..t, view=[-3..7, -5..5]);
end proc:

animate(F,[theta],theta=0..2*Pi,background=plot([cos(t)-2,sin(t),t=0..2*Pi]),
scaling=constrained,axes=none);

Why is it not working?

Thank you!

The command

plots[textplot]({[4.2,1.9,typeset(sin(30°))]},
symbol=point,color=black,font=["Arial","Bold",25]);

will output

Can we have the number 30 in a non-italic format?
Thank you!

Why is the minus sign so weak even in the bold font case? My students sometimes miss it in online tests.
How do we make the minus sign bolder?
Thank you!

I need to get more tickmarks in my plots by reducing the size of fractions produced by Maple.
For example, instead of (3*Pi)/10, Maple gives me (3/10)*Pi. Any help would be appreciated.
I can actually convert all there Maple numbers to fractions, but Maple will not accept these conversions as tickmarks.
Thank you.
