How can I manipulate the scale of dominion?

As you can observe with the graphic can not be examined.

Gracias

Hi everyone,

I have a 2nd order system which I want to solve. But the solver outputs no results after evaluation, just returns to the prompt. Do you know what I am doing wrong?

deq1:=diff(x[1](t),t$2)=k[1]/abs(x[2](t)-x[1](t))^2;
deq2:=diff(x[2](t),t$2)=k[2]/abs(x[2](t)-x[1](t))^2;
sys_ode:=deq1,deq2;
ICS:=x[1](0)=5, x[2](0)=10, D(x[1])(0)=0.1,D(x[2])(0)=0.2;
dsolve({sys_ode, ICS});

thanks.

Good morning.

I have a problem.

My Foco1 function is slower than Foco and how can i do it faster?, because that takes a long time.

thank your for your answer

I want to search maple files for specific texts within the file.  What software will do this?

I recall some mention before about searching for specific texts in maple documents but I cannot find it. 

Hi there,

I got an output

and would like to bring it in the form

.

How do I do that? :)

In fact I don't even manage to collect the factor of 3*beta^2 as follows

I copied a column of figures from Excel and pasted them into an Maple worksheet.  Maple displayed a column vector with the appropriate values.  I set the variable y equal to this vector and was able to verify that, for example, y[3] had the correct value.  However, when I tried to use y[i] after a summation symbol which used i as the index I got the error message "Error, bad index into vector".  The summation expression worked fine when I redefined y by the following:

The original question I posed was whether I could control the output format of a complex array in MathML. I will pose the more general question, how could I customize the MathML output (much like LaTeX output can be customized)?

Regards.

I'm putting together what will eventually be a rather large simulation system that I want to be able to maintain across a reasonably large organization. Do you have any recommendations for Source Code Control/Versioning systems that work with your .msim file format or should I resign our team to exporting/importing code back and forth into Modelica for source control?

Thanks.

so i have a 2D curve f(x), i need to calculate end coordinates of both normal vectors, that are perpendicular to this curve at point x=a, with vector length=l.

simplest way to make it happen anyone?

thanks

When I try to solve a DAE system I got this error:

               Error, (in dsolve/numeric/DAE/applysub) numeric exception: division by zero

Any ideas?
Thanks everybody for help!

Hi to all

I am trying to merge two functions into a single graph. I have discovered the "piecewise" function but however I want to be able to manipulate the variables in both functions and plot a 3D graph to determine the results.

this is what I have so far

Z := proc (t)

if subs(p = 25, (100-p)*(1-exp((-1)*.11*t))/(10.00000000*exp((-1)*.11*t)+1)) < CM and 0 < t then subs(p = 25, (100-p)*(1-exp((-1)*.11*t))/(10.00000000*exp((-1)*.11*t)+1))

of the implicit function 8*x^3+y^3-6*x*y-3=0 with Maple?

How can I save a webpage as a text file? Not the source code. When I save a webpage from I.E. as a text file it seems to strip out a lot of the source code and I end up with a simple text file. Take this wikipedia webpage as an example http://en.wikipedia.org/wiki/List_of_HTTP_headers Now if I use Maple it grabs everything on the page, source code included which I do not want. Is there an easy way or must I create some code in maple (http surgery so to speak) to strip out the excess?

Hello All,

From the list

t1 := [((-4*Pi^2-beta^2+4*beta^2*Q^2*Pi^2+8*I*Pi^2*beta*Q)/(4*Pi^2+beta^2-4*beta^2*Q*Pi+4*beta^2*Q^2*Pi^2))^(1/2), -((-4*Pi^2-beta^2+4*beta^2*Q^2*Pi^2+8*I*Pi^2*beta*Q)/(4*Pi^2+beta^2-4*beta^2*Q*Pi+4*beta^2*Q^2*Pi^2))^(1/2), ((-4*Pi^2-beta^2+4*beta^2*Q^2*Pi^2-8*I*Pi^2*beta*Q)/(4*Pi^2+beta^2-4*beta^2*Q*Pi+4*beta^2*Q^2*Pi^2))^(1/2), -((-4*Pi^2-beta^2+4*beta^2*Q^2*Pi^2-8*I*Pi^2*beta*Q)/(4*Pi^2+beta^2-4*beta^2*Q*Pi+4*beta^2*Q^2*Pi^2...
