I have asked this question in a math forum on the physics forum site and figured it would fit better here:
any and all help would be greatly appreciated!
Hi, I have plotted an implicit 3d plot of an extensive equation into maple, but the particular equation represents a treshold, as it is calculated as the difference between two equations. Which means that everything below the graph represents the case were equation one is bigger than equation two and everything above the graph the opposite. Now by changing the parameters held constant before, I would like to make clear what happens to the chance that one equation is bigger than the other. So to come to the point, is it possible to calculate the surface below and above a certain graph?
I am basically using MapleSim to obtain the equations of motion for mechanical systems and copy
pasting them into a separate Maple document and solvng them numerically. I could work with simple pendulum
and a two link manipulator. But in the case of a four bar mechansism since the system is a closed chain the
number of unknowns ended up being more than the number of equations. In this case, the joint reaction forces
came into play as unknowns. I know MapleSim intelligently does index reduction and solves these equations. But
hye.. iam zarith..
i want to ask u whether there are solution to this differentiation of delta f over delta f.
From format->autoexecute , I wanted to press "clear" but accidentally pressed "clear all" ... now all 200 of my autoexecuted functions (which were very carefully placed and is not easy to remember which ones they were!) have been removed and pressing edit->undo does NOTHING!
I'm so lucky that I save my maple worksheets every time I make big changes (so I have maybe 36 versions of this worksheet!) .... but should maple not be able to "undo" somehting THAT simple!
I've been trying for weeks to solve a system writen in its matrix form like:
M*y(t)'' + C*y(t)' + K*y(t) = F(t)
My system can have like 300 dof. If I generate all de equations and I use the dsolve/numeric command, it works but not all the time. I think that there is a problem with the Heaviside function that I have in some coefficients of my matrix.
I've been reading in forums that it's better to have a first order system to solve complex problems. For that we can create a procedure as explained in the dsolve/numeric/IVP help.
My equation is Y= m.Y^3 + n. B
y: (-1..1) and B: (-60..60) have this values.
How can I fit the m and n parameters by using maple7?
And also how can I plot Y(B) ? Thanks.
I'm trying to export some plots to a .gif file which are then imported to a latex-beamer presentation. Since the presentation uses a non-white background, I want maple to produce gif plots with a transparent background.
What I tried so far is plotsetup( gif, plotoptions="transparent=true" ) but no dice.
As an alternative, setting a RGB valued BGcolor would be ok for now as well ... here I tried setting the PlotBGColor value of my maplerc but this had not the desired effect as well.
Thanks in advance,
I have this same equation in another active thread also with boundary conditions. But now I have INITIAL CONDITIONS INSTEAD. I thought of just starting a fresh post. Here is my non-linear differential equation
x := diff(y(r), r, r)+2*(diff(y(r), r))/r+ C*polylog(3/2, -exp(C2*(C3-y(r)))) = 0
with boundary values D(y)(0)=0 and y(0)=0. C, C1 and C2 are some numbers.
The hint says to use procedure to solve polylog and then integrate the differential equation.
I was wondering if I can get some advice on solving this equation.
Can you please help me to minimize the following cost function with maple 10.I want that " t and T must be greater than zero(not equal to zero) , t < T and C > 0." I tried a lot but I am not getting the values of t and T as mentioned above " ". Also why the solution obtained by the 2 methods below is different ? Which one of them is correct ?
Does anybody know whether there's a library with which I can efficiently compute Minkowski-Sums of Polytopes or Polyhedra?
I was wondering if I can get some advice on solving two integral equations given below for u and b. y(r) is parametrically dependent on 'u' and 'b'.
l := -C1*(int((3*polylog(5/2, -exp(b*(u-y(r))))/b^(5/2)+y(r)*polylog(3/2, -exp(b*(u-y(r))))/b^(3/2))*r^2, r = 0 .. 10.))-C2=0;
I2:=C3*(int(r^2*polylog(3/2, -exp(b*(u-i))), r = 0 .. 10.))/b^(3/2)-1=0;
where C1,C2,C3 are numbers and y(r) is parametrically dependent on 'u' and 'b'.
Hi everybody, I have the following problem:
If I denote by :
He:=(n,k,x)->(-1)^n*(n!)^(1/2)* (GAMMA(n+k+(1/2)))^(-1/2)* LaguerreL(n,k-(1/2),x^2);
Ho:=(n,k,x)->(-1)^n*(n!)^(1/2)* (GAMMA(n+k+(3/2)))^(-1/2)*x* LaguerreL(n,k+(1/2),x^2);
Can I compute the series:
I will be collecting motion data. I believe there will be high frequency errors in the data. I would like to convert the data into the frequency domain and view the frequency amplitude. (I have only a slight familiarity with the Fourier Series and Fourier Transform.)
I have six coupled PDEs to solve. Because of complexity, Maple can not solve them at once, unless I solve three of them first and then satisfy the boundary conditions, then import them into the remaining equation. So it is somewhat semi-manually. The problem is, I do not know how to extract and modify the answer function from the answer of the PDE. Could you please let me know how I can modify the answer and put it back into the other equations?
