1.I don't have Maple 17.

2.I used Maple 2021.

3.I changed  sum to add function.

See atached file.

Update 03.01.2022

I also need a lot of things. Above paper is not free.

Try with maybe works in yours version:

evalf(Int(abs(u(x) - P__2), x = -1 .. 1, method = _CCquad));


I would like to see significant improvement of solving analyticaly(symbolicaly):




4.Integral Transfrom and Inverse like Laplace,Fourier,Mellin,Hankel,Hilbert.

5.Sum Transfrom and Inverse like Ztrans.

6. Linear and nonlinear integral equations.

See, for example, integrals the comparison here.

I would like to see significant improvement of solving numerically:

1.A update a pdsolve numerically higher-order multidimensional partial differential equations.

2.A update a pdsolve numerically to solve elliptic PDEs, but now can't handle.

@KIm Gaeun 

Paste Maple code not a picture. What definition is m(s) ?


% - gives the last result generated.


For : k=2,lambda=1.




h := k - (k - 1)*x;
lambda := k/(1 + k);
ode := diff(p(x), x) = 6/h^2 - 12*lambda/h^3;
bc := p(0) = 0, p(1) = 0;
simplify(dsolve({bc, ode}, p(x)));
is(eval(p(x), %) = 6*(h - 1)*(h - k)/(h^2*(-k^2 + 1)));


@Thomas Richard 

 When can we expect implementation for fractional ODE in Maple?.It is possible in the very near future or not at all?

@Scot Gould 


(diff(sum(x^n, n = 0 .. infinity), x) assuming (-1 < x < 1));


diff(sum(x^n, n = 0 .. infinity, formal), x);



Not so easy to solve, a nonliner ode with power series solution: See

Maybe his helps  see


With  infinite series solution I don't know how to it.

I solved with another method by Homotopy perturbation.If you what  to, see attached file.

Nobody wants to have to type in all your code.It's impolite of you to expect an answer without providing the code to reproduce.

People here generally like users to post (complete) code as Maple code instead of just images,pdf or TeX, so they can copy-paste it(Use green arrow and upload worksheet). It makes it convenient for them and more likely you will get someone to help you.
