hey friends am attaching file in which i have wrote small analysis of my poblem. I have already done this for other problem which does not include term L. But here problem is due to term L. Am no able to write code for this tri daigonal matrix. Please help me in finding unknown coefficients Analysis_of_metho.docx

im unsure on how to start/solve this problem any help would be appreciated

 

∫(x^5)/(x^12-3)^(1/2)

How would i go about integrating

(1)/(x^2+2)

 

I know it has to do something with arc tan but it doesnt match up completely what would I be able to do?

When I am plotting functions with known asymptotes, they do not show, even though the text books show them.Also, I can use the Student Calculus1 Asymptote function to calculate that there is an asymptote, but when plotting, they don't show up.I perused plot/options but cannot find an option that I could enable/disable to have the asymptotes show in the graphs.

Hello every one,

While plotting contours with grid size [200,200] my computer consume too much time to

execute the commond. To have an idea, the current process which I am running right now already

took 2380.22s and 68.60M and still its on.

Any suggestion to make the contour plot process faster?

Thanks

restart;

ode := diff(u(t),t)-f(t)=0 ,diff(f(t),t)+(t+sqrt(t^2-t*n))*f(t)=0,diff(f(t),t$2)+(1-(t+sqrt(t^2-t*n))^2)*f(t)=0;

dsolve({ode},[f(t),u(t)]);

I'm not sure why I get an error in the following simple maple code:

test:=s->fsolve(t^3=s,t);     % Simplified implicit expression for illustration.      

test(8);  % (this yields the answer 2 - good)

plot(test(s),s=0..8);

Error, (in fsolve) s is in the equation, and is not solved for

Why do I receive this error?

Same error occurs with:

fdiff(test(s),s=1);

I'm a casual user of Maple...

Hello,

 

This is more of a tutorial rather than a question because I found some mistakes and because the maple help file was a bit poorly explained and I am posting some additional details.

I am running version 16 of maple and version 7.12 R2011a of matlab.

 

If some of you are wondering how to call a Matlab user function in Maple this is what I have done:

 

First of all in the maple...

Here's a Maple trivia question: There is a Maple symbol that cannot be used as a procedure parameter. As far as I can tell it is the only one. What is it?

I am currently running sucessfully Maple 15 on Macbookpro mid 2009 4G, CPU 2,53 Ghz Intel core duo, NVIDIA GeForce 9400M 256 Mo, OSX 10.8.4

I bought the upgrade to Maple 17, when launching the install package : I have a grey window with a "next" button with slow flashing : impossible to click on it ... so impossible to install the new version

thanks for your help !!

by the way Java installed

best regards

Hi,

     Seems like a silly questionm but the Maple help page suggested usign the option 'interpolation=false' for a numeric dsolve since I ran out of memory (I'm solving a huge matrix DE). But that's not an option in the command dsolve, has this been removed as of Maple 16? Or any suggestions on using less memory? I have 16Gb RAM, 

 

Thanks

I seem to recall from my undergrad days that a cubic polynomial could be readily factored (even analytically) if you appy the assumption that you will have 1 REAL root & the other 2 are complex conjugate pairs.  I cannot seem to find my old lecture notes & see nothing on the web on this matter.

Anyone here have any knowledge on this subject?  I have played with MATLAB & altered the polynomial coefficients such that whenever complex roots do crop...

Does anyone know why png is not listed in the help on plot/devices?  The png device exists and works.

Also, are there any other unlisted plot devices?

When I export my plot to PDF, adobe acrobat says: A drawing error occurred. Other programs see my PDF as corrupt. I would use a .eps file, but my plot has a semi-transparent component that doesnt show up very well as an eps. Any ideas?

 

Thanks
