The problem is as follows:

1- define r := rem(x^3+x+1, x^2+x+1, x, 'q')

2- then once you evaluate this expression, in variables list you may see r as the only variable, whereas q is the quotient variable and it is not provided there.

3- for example if you evaluate q it will give x-1

4- or even you can get the assigned varibles list by anames(user) and it gives both r an q

5- the question is: why q is not shown in variables list

In the Physics package (in Physics:-Vectors, to be more precise), 3-vectors are advantageously represented as

v_:=v1*_i+v2*_j+v3*_k;

with the _i etc. being the unit vectors. I would like to be able to plot these on occasion, either as individual vectors or the line connecting the end points. I can use Component to get at the individual numbers and get this done, but I would like to overload the plot command to do this in a more natural fashion.

By poking...

I cant seem to figure out how to solve this

 

∫(1)/(5+2x^2)dx

 

please help me out thanks :)

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

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
