@acer Windows10 + Maple2019

@acer Thanks!

How do I get the inline answer as in ctrl+= ?

@acer Ok thanks. That's unfortunate.

@acer Thank you. Can you also try the second example "for general a"?

So is it working now with 2019?

@vv Nonono...The answer was not useless since you reminded me about algcurves:-puiseux

I just said that I also "solved" it "manually", and apart from asympt/series/MultiSeries I'm not very familiar with other methods of which there are algcurves:-puiseux , but also else?

@vv That's how I did also solve it, but I thought there must have been some build in function as well...

 

Btw: What do you need the [] in alias(alpha=indets(a,RootOf)[]):  for ?

 

If I have

restart;
f:=RootOf(x^2+1,x)+RootOf(x^2+2,x)*RootOf(x^2+x+3,x);
alias(alpha=indets(f,RootOf)[1]);
evalf(alpha)

 

I can use it to select an operand, but in your case there is only one, so it should be obsolete or?

@vv 

Actually thanks...I completely forgot about algcurves:-puiseux

But do you know why series/asympt has issues with the zeros in rootof?

@Christian Wolinski Not sure what G[1]('%', indets('%', t));  is supposed to do. It's not doing anything for me.

@Kitonum Thanks first, but what if

f:=ln((1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2))*ln(2*(1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2))*ln((1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2))*ln((1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2)) + ln((1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2))*ln((1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2)) + ln((1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2)) + ln((1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2))*ln((1-x)^2*(x+1)^2/((-I*x-I+sqrt(-x^2+1))^2*(I*x+I+sqrt(-x^2+1))^2))

 

?

 

I see that I can first do

op(f)

and then proceed termwise:
 

@Mariusz Iwaniuk I see... ;)

 

Must have misread.

@Mariusz Iwaniuk What do you mean by "trivial" corrections? Do you have an example and do you expect a large jump with 2019?

Can you provide a list of a few "weaknesses" of int, that are going to be fixed?

@Mariusz Iwaniuk why so "late"?

When I do

simplify(polylog(3,1+I) + polylog(3,1-I))

is it possible to look up how maple simplifies ? Apparently it can be transformed into a polylog(3,I).

@Christian Wolinski  How do I replace it?
