So as we know declarations such as theta=var("theta") when output as LaTeX, they're automatically converted to corresponding LaTeX symbols ($\theta$ in this case), but it makes me wonder is it possible for us to use more complicated symbols? Like thetaprime=var("\\theta\\prime") (which obviously doesn't work, I've tried), but I would like to achieve something like this, so when I call latex(eq), all thetaprime variables are converted to $\theta\prime$.

2019-12-14 05:02:05 +0100 asked a question How can I calculate only the imaginary part of a complex number?

So I have the following function which the x will be the difference between two point:

def complexDis(x): return sqrt((x.real()^2)+((x.imag()*-i)^2))

But it seems like i can’t actually operate the .real or .imag number or at least I can’t print it out with N(conplexDis(b-a)) so im asking how can I achieve my goal?

2019-08-27 09:14:23 +0100 asked a question How can I solve line equation in SageMath?

So we know we got standard 2D line equation that looks like y=a*x+b. And now I want to solve the a,b by given a few points. How can I achieve it?

I remember I've seen the solution somewhere, but I just can't find it out now.
