I have a system equations like { a + b = 1, c = a + b +1, d = a + c}

and the sovle function which give me then answer like { a = -2+d, b = -d+3, c = 2, d = d}

I just care about the information in form (name = numeric) like { c = 2 }

and i want the "core" equations which give me that information like { a +b = 1, c = a +b +1 } => {c = 2}

how i can i get the "core" equations of that.

The integrals are

v1:=int((1/(2*Pi) + Q* cos(k*phi))^2/ (1+ beta^2*((1/(2*Pi)) + Q* cos(k*phi) )^2),phi=-Pi..Pi);

v2:=int((1/(2*Pi) + Q* cos(k*phi))^2*cos(k*phi)/ (1+ beta^2*((1/(2*Pi)) + Q* cos(k*phi) )^2),phi=-Pi..Pi);

v3:=int((1/(2*Pi) + Q* cos(k*phi))^3*cos(k*phi)/ ((1+ beta^2*((1/(2*Pi)) + Q* cos(k*phi) )^2))^2,phi=-Pi..Pi);

v4 := int(exp((-1/2)*((psi-theta-k*sin(theta-phi))/sigma)^2),phi = - Pi ..Pi);

In 2010-2011, I persuaded tens of thousands of Russian and Ukrainian students and students in that Maple - a very useful thing.
Testimonials - the number of visits and thanks.
So I decided to resurrect some of my old sites.
Not just for history!

I am having a strange experience with the arrow command.   In the attached worksheet, one can see that plot structures h, i & j and l, m & n are both doing the essentially the same thing:   A vertical line is to be drawn and arrows pointing up and down from the two endpoints are to be added.  The arrows are all of the...

I need help in finding the maximum point of each curve (please see maple file link attached), or if possible display each maximum point (under different "ga") on the 3Dplot

Your help is appreciated

Hello, I'm new to Maple.
when I write:

solve({Wa=Ve,-4*Vd+4*Ve=-4*Wa+4*Wb,12*Vc-24*Vd+12*Ve=12*Wa-24*Wb+12*Wc},{Wc});

Maple gives me no output.
Can somebody help me, what I'm doing wrong? (Maple 9.5)
Thank you for your help! 

 Hello, everyone,
I have two problems in my worksheet.
First, when I specified the value of "s1" for a smaller number, for example 1e-5 or 1e-6, the imaginary part of "an" tends to infinity or -infinity, however, it should be finite.
Second, the value of "an" is instable when specific value of "s1" is choosen. For example, in the attached worksheet, s1=1.9e-4, the value of "an" will be changed when you click "!!!" button several times(that means execute the entire worksheet).

My contour of integration is a semi circle whose diameter rests on the imaginary axis from -ri to ri.  The arc of radius r is on the positive real axis going from -ri to ri.  On the curve I want to have directional arrows indicating that I am traversing this contour in the positive direction.  How do I create this figure in MAPLE?

Dear all, 

I have two questions regarding truncated normal distribution.

1. Is there a convenient way in Maple to compute and plot the density function of a truncated normal distribution? I know that in Maple, after creating a random variable, I can use the function Statistics:-PDF to compute the density function, and use DensityPlot to draw the function. But for truncated distribution, I have to compute it manually by doing integration to compute the normalized...

I have a problem.

I solved a problem, but i like to get one solution for one variable.

I am working with two multivariate functions A and B, with coefficients over a finite field. The x-degree of A is greater than or equal to B, which is greater than or equal to 1, and thus I want to find q and r such that:

A = q*B + r, where q, r are elements of K(y,z)[x], where K is my finite field. Obviously, I would like the x-degree of r to be less than that of B, and r not equal to 0.

My problem is this: the Rem and Quo commands, which will deal with my...

Hi,

I have explored some multi-animation with maple, but I can not change the parameters one by one.

http://www.mapleprimes.com/questions/99833-Procedure-For-ANIMATE-Multiparametrique

Command Explore is analog to Mathematica's Manipulate but the problem in a new worksheet.

How to get Explore like Manipulate in the same worksheet ?

hi, i cant solve the following ODE and Boundary conditions in maple. please help me. i use dsolve and ode analyser but i cant receive and conclusion. thanks.

restart:
#beta:=.01;
#lambda:=.3;
s:=f(x)^2*diff(f(x),x,x)+x*f(x)*(1-2*beta)+beta*diff(f(x),x)*(x^2-1);
 
bcs:=f(1)=0,D(f)(-lambda)*f(-lambda)=beta*(lambda^2-1);
     

I have a strange error when i try to plot an ODE with "numeric,method=gear,parameters=[...]" as options activated. After this implementation I give the parameter a value: ODE(parameters=[123]); -> works. But when I type "odeplot(ODE, [x(t),y(t)],10..20,numpoints=100);" for example, i get the errormessage:

" Error, (in dsolve/numeric/gear) Array index out of range"

But when i remove the option "method=gear", so that the ODE is solved with default runge-kutta...
