please help me here:

i have

p(n):= (2310*n^5+5775*n^4+5019*n^3+(3507/2)*n^2+(409/2)*n+5/2)/(27720*n^7+97020*n^6+132300*n^5+88200*n^4+29400*n^3+4410*n^2+210*n)

how can apprximate p(n) with another polynomial (say: a second degree polynomial in n) or a rational function (ration of two second order polynomials) of less degree of n? and how good is that approximation

thanks in advance

My output consists of a lot of terms (100+) and I need to isolate all the negative (positive) terms. Can anyone help? Thank you in advance.

Hi can someone please help me . My program gives me the correct solution but it crashes afterwards. Can anyone tell me whats wrong with the program please.

 

(D^2y/dx^2 + x^2(y)^2=x, y(0)=y(2)=0 (1)
This is my task:
let :=(D^2y/dx^2)+x^2*(y)^2=x, y(0)=0,y'(0)=b (2)

plot the solutions to (2) for some b values of your choice. What does this tell you about the solution to (1)
so what does this tell me about my solution to (1)?
please could you explain clearly why you can conclude what you can so I fully understand?
many many thanks for your time and effort - much appreciated

I have plotted solution, and can see that for b close to -0.6, the graphs are very similar:

I have:

a(n):=(27720*n^(6)+83160*n^(5)+93030*n^(4)+47460*n^(3)+10689*n^(2)+819*n+5)/(27720*n^(7)+97020*n^(6)+132300*n^(5)+88200*n^(4)+29400*n^(3)+4410*n^(2)+210*n):

now i want to multiply by (n+1/2) that is

a(n)*(n+1/2)

now i want to express it in a simples form. may be like this:

c(n) + d(n)/p(n)

 

 

 

 

I am having problems while installing Maplesim . When i try to Install maplesim on my computer it prepares to install but after it completes then a window appear showing a message that "Please select another location to extract this Installer" .

 

What can I do ?? I have enough space on my Hard disk !!!

 

Plzz Suggest something for me !.

Hello, this is probably painfully simple but I cannot figure it out... so there it goes

there are four set of equations, but only one solution can be assigned to the parameter p (which is the outcome of R1, R2, R3, or R4).

1: if `and`(x4 = 0, x1 > 0) then assign(solpR1) end if;

2: if x2 = 0 then assign(solpR2) end if;

3: if `and`(x1 = 0, x4 = 0) then assign(solpR3) end if;

4: if `and`(x3 = 0, x1 = 0) then assign(solpR4) end if;

Hi experts, I generate two random variables R1 and R2 R1 := random[normald[mu[1], sigma[1]]](1000); R2 := random[normald[mu[2], sigma[2]]](1000); Now I want just the positive numbers of it and save them under K1:=R1^+ K2:=R2^+ Thanks for your help! Regards, Marc

please i try to find a roots of polynom of dgree 17 so i use the command solve();

I find the roots but I 'm not shure that's correct, because I copared them with others in the article it's not the same

So tell me please what can i do

 

 

Hello, I am new with Maple and I am searching a function for the following problem:

I have a vector,
V:=[1,4,8,2]
the maximum of this vector is 8, but I want to know  where the maximum ist. Here it the third entry of the vector.
Is there a function in Maple which gives me the 'place' of the maximum (here 3)??
 

Thanks for your help.

I am new to the joys of Maple and have become a bit stuck.  How do I find the solutions of the following function:

23*sin x + x - 1 = 0

Do I need to plot a graph first and go there?

Many thanks,

Dante.

Dear experts, I use a procedure called Powell. The result of the procedure are the 5 values below. I want to save those results in another variable called MS, but only the second and third value. > Powell(f, Xmin0); [-411.761866103766574, [17.6242885977129257, 82.3757114023303752], 10, 110] -> MS:=(17.62,82.37) The second problem is that I want to put Powell into a double loop. Just for understanding: --> N=1 till 10 M=1 till 10 Powell(f, Xmin0); End M; End N; So that I get 100 values of MS:=(....,....). That I want to save in a matrix.

Dear Experts,

I got a warning with this sheet. I did a calculation in MathCAD11 without a warning - but with Levenberg-MArquardt. This method is missing in Maple12. How can I solve this fitting problem with Maple12 without a warning? Thanks in advanced.
