Hi,

I have been solving a system of non-linear ODE's for their steady states. This involves solving the rhs of the ODE's =0.

Hence I have been using "solve" in maple to solve a non-linear system.

Recently I have added more detail to the problem and now I am solving eight equations for eight variables and i've left overnight and maple still didnt find a solution. When sigma1=sigma2=0 below the problem is effectively 5-d and maple breezes through the calculation.

hello,i have a problem i have to program analytic solution of heat equation of a rod with two heat sources if you can help me by anything please d'ont hesitate, thank you.

Solve Differential Equation :(3x-y)*dy/dx=2x

Hi guys,

I would like to solve a system of equations and inequalities with symbolic parameters (D, E, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z) for several variables (a, b, c, d, e, f, i, j, l, m, n, p, q, r, s, t, u, v).

Unfortunately the command below does not work. I get the message "Warning, solutions may have been lost".

"Solve({ l-u=0, m-v=0, n-u=0, p-v=0, Y+q-u=0, Y+r-v=0, Z+s-u=0, Z+t-v=0, (a-P*M)*l=0, (b-Q*M...

Hello, everyone. I have been messed up by a system of 50 nonlinear parametric equations with 50 unknowns(see the code in the file named nonlinear ). Since I am new to Maple, I don't know whether it is possible to make such a system work out by software. I've tried the SOLVE and FSOLVE command but get no result. Are there any other ways or toolbox for such kind of systems? Is there any typing wrongs in my code? I am sincerely looking forward to  receive any ideas...

Good afternoon Professor.

I am M.Anand working for SRIIT, as Assistant Professor in Mathematics in Hyderabad, INDIA.

I request you to help me How to write c-programming codes to solve the linear system by using Gaussian elimination, conjugate gradient method without preconditioning and Conjugate gradient method with preconditioning?

With thanks & regards.

Hello,

I need to model universal joint and spherical joint with spring elements.

Contrary to the revolute joint where there is an option to put spring element, i don't find this option in the universal joint and the spherical joint. So is there a simple solution to model spring in this kind of joint.

I hope that i shouln't have to build the joint with several revolute joint in serial.

Thank you for your help.

Hello,

I have a little question concerning the definition of the rotation matrix in the rigid body frame.

The rotation matrix is defined like that in the help menu : "The rotation matrix that transforms a vector expressed in the outboard frame to the inboard frame".

Consequently, we have :

Is there any direct approach like Jacobi,Gauss-seidel, & SOR methods in Maple to solve a given linear system of equations by using Conjugate gradient method & Preconditioned Conjugate method.

I request you to help me out to generate Maple commands to solve.

Can you please graph this function, as well as find the domain and range in interval notation?

This is my question that I posted at http://mathematica.stackexchange.com/questions/32338/is-there-a-triangle-like-this "I want to find the numbers $a$, $b$, $c$, $d$ of the function $y = \dfrac{a x + b}{c x + d}$ so that the triangle $ABC$ with three points  $A$, $B$, $C$  have integer coordinates and lies on the graph of the given function, then the centroid of the triangle $ABC$ (have also integer coordinates) is also lies on the graph".
