Why does show("$\Theta$") display the capital Greek letter,
but show("$\theta$") gives "heta"?
Thank you.

Have zeros of order 2 too, so the sign change doesn't help in general, but
may work for some zeros. Thank you!...

Thank you, that makes sense. My Python function is not continuous though,
has poles, so I'll probably have to plot it to find its zeros...

Thank you, that's helpful. Is there a way to get all roots of a Python
function on an interval?

Thank you, so what to do for Python function? Matlab had general purpose
'optim(f)' if my memory is right...

How to plot output of solve() on coordinate plane?
For example: show((solve([mu^6==1],mu))) gives symbolic LaTex output
Thank you...

My new worksheet @SageMathCloud does not "see" a function defined in a

What's the path to a Sage file? How to attach it to a worksheet

Thank you...

The following matrix operation produces wrong answer in online Sage:
M=matrix(RR,[[7,3,10,13],[1,1,2,2],[1,2,3,4],[1,3,5,7]]);det(M);invM=M^(-1);invM*M;det(invM)
If one changes RR to QQ the answers turn correct. Or it is enough to change
one corner matrix entry to:
M=matrix(RR,[[8,3,10,13],[1,1,
