Hi,

QQ.mw

I want to find the inverse function of the given function h(m),and also plot the inverse.I can't find any help to evaluate the inverse function in an explicit form.I plot the inverse though,but why its so ugly?How I can customize its domain & range?

I'm trying to use dsolve to get a numeric solution to a series of differential equations I have. I've got:

G := 1;

M := 1;

pT := 2;

OrbitEnergy :=  (r0) -> -1/r0+(1/2)*L^2/r0^2-L^2/r0^3;

OrbitDEs := diff(r(tau), [tau$2]) = -G*M/r(tau)^2+L^2/r(tau)^3-3*G*M*L^2/r(tau)^4, diff(phi(tau), tau) = L/r(tau)^2, diff(t(tau), tau) = sqrt(r(tau)/(r(tau)-2*G*M)+(diff(r(tau), tau))^2*r(tau)^2/(r(tau)-2*G*M)^2+r(tau)^3*(diff(phi(tau), tau))^2/(r(tau)-2*G*M));

Dear Sir / Madam,
Could you recommend me how to find the square root of the complex equation correctly?
My equation looks like this
sqrt(complex_equation_1^2 + complex_equation_2^2).

Hi,

I've been using Maple 13 installed on Ubuntu 10.10, but noticed some issues with 3d plots, Maple does not allow me to rotate and drag around 3d plots as it does on my windows 7 boot on the same machine, instead it struggles to even do the 3d plot in the first place and then usually crashes on trying to rotate it.

Also I occassionally get empty GUI boxes when I go to save as etc, instead of any content just a gray pop up box.

Anyone...

Friends,

I am very beginner of Maple softs, in order to proceed with my project i need to model a simple Human Knee joint and  to do its simulation, Somebody please help on this, otherwise i cant able to proceed with my project.

Hi!

Exuse me, can somebody help me???

Maple kills my very important work. I work with Maple 13 and wrote big scientific programm.

I restart my computer, when i try to open file, which works normal yesterday, i saw something like this:

//   How do yo want to open this text file? //

Maple text     Plain text    Maple input   Cancel

Everything i try - no result,...

I'm running a for loop to find a numerical solution to a linear system of equations.

x1:=1

x2:=2

x3:=3

for i from 0 to 10 by 1 do

y1:= f(x2,x3);     <-------------- these are functions of variables solved using the initial approximations above.

y2:= f(x1,x3);

y3:= f(x1,x2);

x1:=y1;    <-------------- Reassignment statements

x2:=y2;

x3:=y3;

end do;

Hello,

I want to solve the differential equation and put the solution in a list to be able to animate the pendulum.

tipe6 := proc (longueur, thetaInitial, rayonBoule, nombrePoints)

local eq, sol, valeurstheta, x, y, plotseq;

eq := ((1/2)*longueur^2+(1/5)*rayonBoule^2)*(diff(theta(t), t))^2+g*l*(cos(theta(t))-cos(thetaInitial)) = 0;

sol := dsolve({theta(0) = thetaInitial, (D(theta))(0) = 0, eq}, theta(t), numeric);

Hi!

I i have a 2nd order ODE where i want to chance the derivatives of x(t) and y(t) exactly at sqrt(x(t)^2+y(t)^2)=1 ,or before, as close to 1 as possible.

I found "event=" in/dsolve/numeric/events, where i can define the trigger and the action.

What is the difference between: "event=[[sqrt(...)-1,diff(x(t),t)=...],[sqrt(...)-1,diff(y(t),t)=...]]" and "event=[[sqrt(...)-1,[diff(x(t),t)=...,diff(y(t),t)=...]]]", because i get different results, which one is the correct form?

Hi, I would like to numerically work out the profile of one expression (integral and BesselK function involved). But the computer was just jammed and came out nothing after long time waiting. I attach the worksheet below and maybe you could have a look at it or directly run it in your machine to check what is wrong, either my computer or the code itself. Thank you very much.

I am new to maple, and looking for som tourturial to get me started. My school dont offer any education in the program.

Can maple do the same things as matlab? i have a little program i wrote i matlab. Is it possible for me to write that i maple?

Hey Mapleprimes,

 I have a set of 3x4 Matrices and i need to filter some out, but cant find the right maple commands. Example Matrix:

[2 4 0]    row 1

[0 2 2]    row 2

[0 2 2]    row 3

[4 4 4]

row 2 = row 3

1. If all elements of a matrix have a common divider, such as 2 in the example matrix, I need to store the simplified matrix, meaning the one with all values divided by the common divider....

I am setting up a new machine.

I was running Maple 13 on another machine running Fedora Linux 13.   I don't remember if I had any problems setting it up, but it was running fine.

But I removed it from the old machine and installed it on the new machine which is running Fedora 14 Linux.

Maple 13 loads but I get a message from SELInux about a problem with Maples's mserver and execcstack.   ...
