Hello,

I would be grateful if other users of Maple TA could post their experiences of the Equation Editor here. I have used it in Maple TA 5 (on premise) and 8 (hosted) and in both cases it is incredibly slow to load, has errors with out of date certificates (I've been told these will be fixed in version 9), and sometimes just won't display an equation from the question at all. I don't think I'm doing anything wrong (I position my cursor on the equation...

Hi,

I am aplying a simple energie balance with some simplification, and i am implementing it on maplesim.

The component has the following equations:

Am i missing something? Do i need any aditional equation to maplesim know to where should the fluid be moving when Qjacto is positive or negative? Why do i have...

how to evaluate to equation (5.9) in page 195 from rodrigues formula?

rodrigues := exp(x)*(x^alpha)/n!*Diff(exp(-x)*(x^(n+alpha)), x$n);rodrigues := subs(x=2*p, rodrigues);rodrigues := subs(alpha=1/2, rodrigues);

Dear Friends. I solve a group of linear equations and the memory is not enough and i can't

adding a new hardware to the computer.i increase the virtual memory of the computer from some chose for the operating system

but it seem to me the Maple use the memory from the hardware only.I want to know is there any method to make the Maple using the virtual memory for

the computer

hello every body

how can i solve this equation with respect to z

a, b are constants

3a(1+z)^2=2(a(1+z)^3+b)^(1/2)

Hi all,

I have the following equation: A.X = Y

A is a 14x7 known matrix, Y is a 14x1 known matrix, and X is a 7x1 unknown matrix Would you please how to find the solution X of this equation in Maple.

Thank you so much,

STH

PS: I attached matrices A and Y in this postA.txtY.txt

hi,

I am trying to make a custom on maple but when i get an error on dynamicSystems saying:

> sys := DynamicSystems[AlgEquation](eq, inputvariable = [Altura(t)], outputvariable = [Teste(t)]);Error, (in DynamicSystems:-AlgEquation) algebraic equations cannot depend on past/future values of the input/output

But if i change AlgEquation to diffEquation i get no error. I dont have any diff equation on the system. This is happening with one of the "equations":

Hi guys. I need to do a Runge-Kutta method to solve two equations and I'm having trouble at using functions. My program is as shown below:

restart; A := Matrix();

dt := 0.1e-2;

diff(x(t), t) := v;

diff(v, t) := a(x(t), v);

xo := 0; vo := 0;

for i to 1000 do

xn := xo+v.dt;

vn := vo+a.dt;

dx1 := vn.dt; dv1 := a.dt;

dx2 := (vn+(1/2)*dv1)*dt; dv2 := a(x(t)+(1/2)*dx1, (1/2)*dv1)*dt;

dx3 := (vn+(1/2...

Hi all, I am having two simultaneous equations , i dont know how to solve these two equations, any one help to solve these equations..

Im knowing the approximate/accurate answer for the equations, These are the values for my equations

alpha=1.53222, beta= -0.555345, kappa= -0.399943,

Thank you

I am working on a project where Maple's output is fed to another software which requires all it's input in specific format. So, I want to print this expression,say

y=+2.*x+.2, in this software, but it takes input as

y=2*x+0.2, So now I have to change

+2. to 2.0 or 2 (if it's starting of the equation)

-2. to -2.0

.2 to 0.2

Is there any way to convert all the numbers in the equation to...

I am working on a Maple project and it require me to pass a differential equation in a specific order like

x'=y & y'=x^2.(It is differentaiting w.r.t 't'(say))

However when I convert the equation into string it converts something as

diff(x(t),t)=y(t) & diff(y(t),t)=x(t)^2

Is there any way to stop maple from evaluating into maple/math format?

Is there any way to pass an equation without changing it's existing form?...

What is the number of all the solutions of the equation frac(x*floor(x)) = 1/2 belonging to RealRange(1,100)? How to count it with Maple?

I'm trying to solve system of linear and nonlinear equations with inequalities and it looks like this:

SX := solve( [ seq(diff(EX,WX[k+1])=0, k = 0..m), # these are linear ...

x = a*(3*cos(t) - cos(3*t))y = a*(3*sin(t) - sin(3*t))

is there a library or function to convert above parametric equations into one equation in terms of x and y?

sys := x = a*(3*cos(t) - cos(3*t));k := solve(sys, t);simplify(subs(t=k[1], y = a*(3*sin(t) - sin(3*t))));

any simpler form?

I have this matrix with coefficients that I need to estimate;

I get there after some simple calculations and I know that my matrix it´s equal to the zero matrix; I have something like:

A:=Matrix(3, 3, [5*a-4, 5*sqrt(a) *sqrt(b)-5, 7*sqrt(a) *sqrt(c)-6,

8*sqrt(a) *sqrt(b)-5, 8*b-2, 8*sqrt(b) *sqrt(c)-9,

4*sqrt(a...
