I have the following sequence: n²/n²+31n+228.The question asks me to use an appropriate conditional statement to find N such that absolute (x_n-x₀)<epsilon for every n>=N. I found N but i don't know how to find it using Maple17.Can you please help me?

Hi. I'm hacing trouble writing a maple procedure for the question below, can anyone help?

Write a maple procedure which takes as its input the vectoeat u1 and u2 and the eigenvectors lambda1 and lambda2 where u1,u2 are element of R^2 and the lambdas are real numbers.

If u1,U2 is linearly independent then the output is the matrix A an element of R^2x2 with the property that Au1= lambda1u1 and AU2=lambda2u2;

if u1,u2 is linearly dependent then the output is the statement "not an eigenbasis".

I I then have two inputs which I have to do but I'm not sure on how to write the procedure. Any help will be much appreciated.  

Thanks :)

Dear all,

I developed a program to solve f(x, y) = 0 and g(x, y) = 0, I obtained as results (x=2.726, y=2.126) . running the same program another time it gives (x=2.762, y=1.992). how to explain this?

> fsolve({f(x, y) = 0, g(x, y) = 0}, {x = 0 .. infinity, y= 0 .. infinity});

Thanks in advance.

So have to calculate frequency response of RLC-circuit
Long story short - I can't get how to solve something like this
solve(abs(I+x) = 1)
Obv - the answer is 0 or -I, but i get 1-I, -1-I instead

It's been a couple of years since I last used the Excel add-in for Maple 17. It was working before, but now it isn't.

When I click any of the Maple icons in the Excel Add-Ins -> Custom Toolbars tab, I get a Visual Basic run-time error 453, "Can't find DLL entry point vbLoadMapleCursor in WMIMPLEX". The only choice in the dialogue is End, after which none of the Maple icons respond.

When I quit Excel after trying this, I get the same error dialogue except the message refers to vbMapleQuit. I select End, and then Excel exits. (If I don't touch the Maple icons during an Excel session, then of course no VB error dialogue referring to Maple pops up.)

An answer to a ten year old MaplePrimes question on the Excel add-in suggests editing the Excel 2010 32-bit path registry entry. Indeed my HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Excel.exe Path key has no reference to Maple. However that info is so old, for Maple 9.5, that I hesitate to use it. I tried though. As suggested in that question, updated for Maple 17, I tried adding ";C:\Program Files (x86)\Maple 17\Excel\" to the end of the existing Path key entry, but I still get the same VB error. I also tried adding ";C:\Program Files (x86)\Maple 17\bin.win\", and both: "C:\Program Files (x86)\Maple 17\bin.win\;C:\Program Files (x86)\Maple 17\Excel\". I tried disabling and reloading the add-in from the Excel Add-Ins menu. Interestingly, even when I disable the add-in, the toolbar icons still show.

Anyway I'm at a loss how to proceed. Any help is appreciated. --Graham

So im trying to solve multiple ODES using dsolve(numeric) but I jsut cant get it to work.

I kep getting this one error: 

Error, (in f) unable to store '-HFloat(0.020918994979034728)-HFloat(0.09184018333019917)*I' when datatype=float[8]

This is my uploaded file 

(for some reason the uploaded file didnt show the error at the bottom so i just pasted it in the spot it would appear.

Hello everyone, how can this error be corrected

Thanks.

I'm not really an expert in maple. I'm stuck with a problem that could be related to the precision of the computational engine...

I defined a function which is relatively complicated as follows:

m := proc (x, l, T) options operator, arrow; (exp(l*(x-T)/(1-exp(-l*T)))*exp(l*T/(1-exp(-l*T)))*(1-exp(-l*T))+(2-exp(-l*T)-exp(l*T))*exp(l*(x-T)/(1-exp(-l*T))))/(exp(l*T)-1)-(l*(x-T)*exp(l*(x-T)/(1-exp(-l*T)))-2*exp(-l*T)+4-2*exp(l*T))/(exp(l*T)-1) end proc

whenever i simplify the equation or factor some of the terms, I get completely different results.

As an example, you can define this function as follows

m := proc (x, l, T) options operator, arrow; (exp(x*l/(1-exp(-l*T)))*(1-exp(-l*T))+(2-exp(-l*T)-exp(l*T))*exp(l*(x-T)/(1-exp(-l*T))))/(exp(l*T)-1)-(l*(x-T)*exp(l*(x-T)/(1-exp(-l*T)))-2*exp(-l*T)+4-2*exp(l*T))/(exp(l*T)-1) end proc

By drawing the function, you can see how things get messy.

plot(m(450, (1/250)*x, 250), x = 0 .. 100)

I know the problem occurs as a results of computation round-off. How could I ameliorate that? I have already increase the precision in the option menu, but that didn't help. By the way, how can I be sure that the anwers maple gives me is correct, except using my intuition?

Hello everyone!

i want to make a triangle which height's is a. Sorry, my English is not very good!

And I writed it by C language, but It is not right in maple. and I don't know. Can you help me? thank you very much! triangle.mw

with sin(x) and cos(x). how to draw  this graph:

question.mw

thanks you!!!

Download question.mw

why the the software can't plot the function like x^(4/3)*sin(1/x) or x^(1/3)

it could only plot where x>0,but the value is does exist where x<0.

Thanks in advance for your help.

Hi Everyone,

I want to draw a 3D cylindrical object with follwoing constraint:

(1) For z=0 to 5, it should be a cylinder with radius 2 units

(2) For z = 10 to 20, it should be a cylinder with radius 8 units

(3) Connecting piece between z=5 to 10 is a type of cylinder such that its radius increses from 2 to 8 as z moves from 5 to 10.

I know how to draw (1) and (2) individually, but can't make a connecting object.

Can anyone help me drawing that object?

Thanks in advance.

hello

I have recently install Maple17 on my computer (Windows10) and I need to use some Greece alphabet such as ß but I look everywhere in maple's icon and I just could find capital Greece alphabet.

does anybody know how can I find those?

The plot command outputs a graph of symbols where the line is made up of "H"s, vertical lines on the axes are "+"s, horizontal lines on the axes are "-"s, and intercepts are "*"s.

How do I fix this problem so that the graph displays a graph normally?

I have several *.mw files which I have built seperately. Now, for readability reasons, I would like to create a Master document, which will ues the first files, and then generate a PDF document.
I tried the read command, but it does not recognize the files.

Any help is appreciated.
