I have noticed that after entering the login/password "My Maple Cloud" section momentarily appears and vanishes and I remain not logged in. I am able to login via web browser, but I would prefer to login via my Maple.

@9009134 Just like Carl Love pointed out, the name differs from its appearance. That is why I had to use:

S := remove(type, indets(B, function), trig);

to collect the functions. You can get the names & substitutions from this also:

S2 := (sort@[op]@map2)(op, 0, remove(has, S, diff));
S3 := [f__31, f__21, f__11];
lprint(`=`~(S2, S3));
subs(`=`~(S2, S3), eval(W));

@9009134 I think you mean to use subs command: subs([u__r=f__11, u__theta=f__21, u__phi=f__31], eval(W));

@9009134 
 

#instead of
#W := map(proc (S) ([op])(S); map2(map2, op, [1, 2], %) end proc, W)
#use
W := map2(add@map, `*`@op, W);

@acer You wrote:

Na0 := NumberTheory:-Divisors(coeff(p,x,0));

 

Nan := NumberTheory:-Divisors(coeff(p,x,degree(p,x)));


I think it should be:

Na0 := NumberTheory:-Divisors(tcoeff(p,x));

 

Nan := NumberTheory:-Divisors(lcoeff(p,x));


 

I have one question. What do you use to read contents of a module? I find them very obscured.

@Carl Love It is a small step in the right direction.

It sounds like you are looking for the annihilator of sin(erf(t)) and annihilator of cos(erf(t)). Am I right?

@9009134 If you used radius r0 for your cylinder plot and want to present it with radius r1 on a torus of radius R0: F(R0, r1/r0, (2*Pi)/0.5); The third coordinate lets you transform z coordinate into the angle by scaling z.

Do you intend to use cylinder plot in your solution?

also try with
f := F(1, 2, (2*Pi)/0.5);

@ Thank You for verifying this.

@Carl Love I did not want that heap on display in any form... I now attach it to the answer. My apologies.

@Zeineb Ok. So what you want is variable reordering. You have inequality displaying a function of x, sorted by ranges of x. Instead you want the inequality displaying a function of a, sorted by ranges of a. Right?

Properly formatted image. Full Sized

Muting the difficult exponentials in alpha1, alpha2 and solving for mu1, mu2 we get rational expressions. In particular the rational for mu1 expanded numerator and denomerator have 315719 and 417318 terms respectively. One can doubt Digits:=10; will be enough or the fact this will be solved for something other than the trivial (mu1, mu2, alpha1, alpha2) = (0., 0., 0., 0.).
