MaplePrimes Questions

Hello I have the following system of equations and I want to solve for rho1 and z1

E := (1/2)*(1/rho1^2+1/rho1^2)-1/sqrt(z1^2+rho1^2)-1/sqrt((R-z1)^2+rho1^2)-1/sqrt(z1^2+rho1^2)-1/sqrt((R-z1)^2+rho1^2)+1/R+1/sqrt((2*rho1)^2+(R-2*z1)^2);

Er1 := diff(E, rho1);

Ez1 := diff(E, z1);

solve([Er1, Ez1], {z1, rho1});

The system is a function of R.

The solve command spits out Kernel lost after some time. So my question is how can I solve it ?

My version is maple 13. I tried to find out how to solve system of linear equations like A*X=b, whre A is a matrix and X and b is a vector, the solution is X:=linsolve(A, b),

But, the system just return the formula of linsolve(A,b) where it replace A and b by their forms of matrix. Simplely , the software doesn't show the result. I tried also evalm(linsolve(A,b)) , but it just return dezens of linsolve(a,b).

There seems to exist no such facility with Maple 17, although that was present for Maple 16, 15, ...  and it seemed to be useful. Please explain its absence.

hey friends please check this code and help me in removing errors. working_nonlinear.mw

there is a triangle, one side is t, another side is sqrt(1-t^2), however this do not need sqrt

i use sin law, can not dsolved the following equation, it can onlyl be solved for right angled triangle

is it only in circle's triangle be solved? 

besides triangle, the goal of mine to use another shape 

ode := diff(u(t),t)-f(t)=0,diff(f(t),t)+t*f(t)=0,diff(f(t),t$2)+(t*sin(a)*sin(b))^2*f(t)=0;  

ode := diff(u(t),t)-f(t)=0,diff(f(t...

Hi,

 

I have the following function to plot

Hello all,

 

as in title I have trouble with exporting simulation result data in MapleSim.

Storing the result works fine, but the problem occurs when it comes to exporting (and viewing the result again).

The console says

"at offset 67895293 in `C:\Users\YUKIHI~1\AppData\Local\Temp\_result2_68856801825556689291274099867619489771.m`, unexpected end of file "

 

the simulation settings are as follows.

I'm working with saving procedures to repositories for the first time.  I have been using the following documentations as a guide:
http://www.maplesoft.com/support/help/Maple/view.aspx?path=libname
http://www.maplesoft.com/support/help/Maple/view.aspx?path=repository%2fmanagement

Anyhow, when I run this code at the start of my program:


restart;
savelibname :="/Users/ryderbergerud/Documents/School/year4/Summer/Research/myLib";
march('create'...

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 :)

hey friends am attaching file in which i have wrote small analysis of my poblem. I have already done this for other problem which does not include term L. But here problem is due to term L. Am no able to write code for this tri daigonal matrix. Please help me in finding unknown coefficients Analysis_of_metho.docx
