Hi guys,

I am fairly new to Maple so please go easy on me!

I have seen the Mathieu equation in my chemistry book regarding quadrupole mass spectrometer. I want to know how I can use Maple to solve the equation and to plot a 'stability diagram'?

The equation is seen here (in this link):

I have Maple 12. I am trying find integer partition of 20 into size 5 each. This can be accomplished in mathematica, using the command of 

IntegerPartitions[20,{5}]

Maple does have Partition command but there is no way to use that command to produce an output of size n partition.

For example Partition(20,5) results in partitions of 20 with 5 being the largest integer. That is not what I want. I need to...

How do i solve a simple trigonometric equation? For example sin(2*x) = -sqrt(3)/2.

I am unable to find where the problem is within a plot. Here is the error message: Error, (in plot) incorrect first argument [(k-1)*r*(cos(t)+cos(k-1)*t/(k-1)), (k-1)*r*(sin*t-sin(k-1)*t/(k-1)), t = 1 .. 1, r = 1 .. 1, k = 3 .. 3]

Is there a symbol or something that i am supposed to be looking for in the error message so i know where the error is occuring?

How to draw slope field associated to differential equation: dy/dt = sin(ty) on Maple software?

I know I can use try catch but why doesn't this work?

is(tan((1/2)*Pi) = "Error, (in tan) numeric exception: division by zero")
Error, (in tan) numeric exception: division by zero

It is a string value error that should be true in the test shouldn't it?   

Hi,

I asked a similar question some time ago : http://www.mapleprimes.com/questions/123925-Shortcut-Key-AltShiftF6.

I'm still on Maple 13, and I still have not found a way to switch between tabs/windows using the keyboard.I am in the one Maple session (ie I haven't started a new one).

I tried all suggested combinations, including all combinations of Ctrl, Alt and Shift...

Hi,

A simple question. How do you echo 2+2 to the output without Maple calculating it and putting 4 in the output ?

thanks,
Andrew

Firstly applogies for if this question has been asked before.

I am trying to plot a simple epidemic model for where I can change the rates.

My equations are:

de1:= diff(X(t),t)=a*X(t).Y(t);

de2:=diff(Y(t),t)=a*X(t).Y(t) - b*Y(t);

where X is susceptibles and Y is infected.

I would like to be able to produce a graph with the susceptible and infected plotted. Where i can change the initial conditions of X(0) and Y(0) using sliders...

Let r is radius of circle inscribed and R is radius of circle circumscribing atriangle ABC.

Prove that p[tan(A/2)+tan(A/2)+tan(A/2)]=r+4R where p=(1/2)(a+b+c).

I have two inequalities in the complex variable z, called "ineq" and "ineq2".  When I issue the following plotting command, I can show the region of the complex plane that satisfies both inequalities:  It appears as a black region:

plots[implicitplot](eval(ineq = ineq2, z = x+I*y), x = -8 .. 8, y = -8 .. 8, gridrefine = 3, filled = true)

Now, I would like to generate a similar overlap plot, but for three inequalities,...

Hello,

I just bought a new PC with Windows 7 Professional 64bit and wanted to install my old Maple 12. I have a notebook with Windows 7 Home Premium 64bit where it runs without any problems. However, Maple 12 does not start whether I put it on compatibility mode or not. There are just two error messages showing up:

Maybe someone can help?

I have a question about the accuracy of Maple functions subs and evalf. I have some expressions such as the following: (more complicated). Let's call it f(n).  f(n) is not a polynomial in n or a rational function. It is a function of n involving exponents and four operations. When I plug in a large n in such an expression, would the answer I get (using evalf with some custom accuracy) be exact?  I am trying to prove f(n)/n >= constant....

Maple experts, please help...

I am facing hard time with ODE functions...:(
I would like to know if there is any command or algorith that could actually clear the solution of "dsolve" command,what I mean... let's say I have ODE function of one indeterminate "y(t)" and its general solution is obtained from dsolve command by setting certain initial conditions. Now, I need to remove that general solution from the system memory so as on next call of ODE function the "y(t...

Hi, can anyone help me with this questions? Thanks!

Use maple to find the general solution to the following system of linear equations:

2x₁  + x₂ - x₃ +3x₄ = 2

x₁ + 2x₂ -x₄ = -1

3x₁ +2x₂ -2x₃ +x₄ = 1
