Hello.

I am solving a problem using the homotopy perturbation problem, I have the code already but I don't know how to fix my f₀(eta) = 1 - e^-(eta). f₀(eta) is the assumed solution. 

Thanks.

Why don't these two work?

(f@seq)(i, i = 1 .. 2);
                        f(i, i = 1 .. 2)

(f@add)(i, i = 1 .. 2);
Error, (in simpl/relopsum) invalid terms in product: 1 .. 2

I was expecting f(1, 2) and f(3).

Hello,

I would like to ask, if somebody knows whether the CAD Toolbox is included in the students version and if not how much is it?

Thanks!

Hi,

Could you please help me in solving this problem ?

• N is the number of row, about 10^4 in real applications
• P is the number of columns (about 5)
• A and B are two NxP matrices
• C is the Nx(2P) matrix defined by
  • its 2*k-1 th column is the k th column of A
  • its 2*k th column is the k th column of B

What is the fastest and less memory consumming way to construct this matrix C ?

Thanks in advance

 

I have a matirx

where ci and si represent cos(θi) and sin(θi), respectively. I need to substitute

What is the right way of using trigsubs command?

collect((sqrt(x)+y)^2, [x, y], distributed);
                                       (sqrt(x)+y)^2

I think this is wrong. Documentation says that collect supports fractional powers of the variables, so in this case collect should return x+2*sqrt(x)*y+y^2.

Why when I write (9b² - r² - a² cos(theta)²)² maple changes to (r²+ a² cos(theta)² - 9b²)² ? Would anyone know how to block this change?

Thanks!

write a maple script to find the relation on set s is

1)reflexsive

2)symmetric

3)trasitive

How do I change my input of variable current, I1, to I, without violating the imaginary unit?

After waiting about six hours for the worksheet to be executed, I finally lost hope and stopped it. (My CPU usage was stuck on 100% the whole time and I almost ran out of memory) Is this evaluation time normal and should I have waited longer, or is there a problem with my worksheet? (I'm uploading it here) Or is it possible that the equation cannot be solved by Maple at all?
