I found some old Maple 6 worksheets that I wrote in 2003 and I want to see what's in them and probably transfer at least some of the content to new worksheets.  Most of them I can view just fine with Maple 16 standard interface but at least one of them comes out looking like all of the lines have been printed on top of each other --- completely illegible.  Now I can read the worksheet using Maple classic interface on my machine at home, but both of my machines at...

Hello all,

I just recently got Maple 15 re-installed for my Chaos Theory class, and am having a bit of difficulty remembering how to plot iteration functions..

An iteration function, obviously, is one where the calculated values depend on the previous (or initial if it is the first plotted) values.

Where the general form of the equation I want takes:

X_n+1 = k - (X

Hi All,

Im solving a system of five second order differential equations, dsys, with five degrees of freedom, using the command:

> Sol := dsolve({dsys, ini}, {phix(t), phiy(t), phiz(t), thetax(t), thetay(t)}, numeric, output = listprocedure, range = 0 .. ts)

This solves the system with initial conditions ini from t=0..ts. 

With the command: > odeplot(Eq75, [t, Z2], 0 .. ts, numpoints = 100), I plot Z2, which is a function of the degrees of freedom, form t=0..ts. ...

It appears that Maple will not install on Windows 8. When will this be fixed or can you provide a solution?

Thanks

Why Maple not simplify
simplify((x*ln(x)-ln(1/(1+x))-x*ln(x/(1+x)))/((1+x)*ln(1+x)))
(result = 1) ?

Hi. i just installed Maple 16 on my computer, but i doesnt work. Everytime i try to open it, it just loads forever. i Tried to install maple 16 32 and 64 bit, without any luck. I have tried to run it as administrator, and in combability mode, still nothing.

I have windows 7 home premium 64 bit.
 

This question was asked before but because of the curiosity, I 

bring it in the light again. We have a system of odes

restart:with(plots):

a := 1; b := .5; d := 1; omega := .4; h1 := 1+a*cos(x); h2 := -d-b*cos(x+omega);

F := Q-1-d;

de:={alpha*(diff(f(y), y, y, y, y))+G*(diff(theta(y), y, y))+B*(diff(phi(y), y, y))

+6*beta*(diff(f(y), y, y))*(diff(f(y), y, y, y))^2+3*beta*(diff(f(y), y, y, y, y))*

(diff(f(y), y, y))^2 = 0,

I have a function that I want to evaluate to a numerical value.

It has euler's numbers and natural logarithms as well.

The function is defined at h:= x-> expression.

When I call h(value), then it only simplifies and won't produce a numeric value.

What do I do?

Hi!

After a matrix calculation in maple I might end up with a matrix with common factors, like this ...

Now this matrix has elements with common factor that I want put as a factor outside the matrix. How can I do this?

Thanks :)

Dear All,

I am trying to solve the equation shown in the attached file but can't get the required answer, any suggestions?

I shall be very thankful.

A(n,q) = I(n)*Z(q)/2 * Sum((cos(nwt - qptheta - (n-q)(i-1)2*Pi/3)+cos(nwt + qptheta - (n+q)(i-1)2*Pi/3)),i=1..3)

With n - q = ...-9,-6,-3,0,3,6,9   above equation becomes

I have written a procedure that creates lists of numbers (for later plotting, but that is irrelevant here). These lists I have programmed as 1-d rtables (Vectors and Arrays). Since I do not know initially how many entries the procedure will generate I am using programmer indexing (with round braces) so the Arrays and Vectors get extended as needed, 1 entry at a time. Basically; I dynamically allocate storage in this way. Maybe not the most efficient way but should work for now.

Hello every one,

I am trying to solve a system of 5 odes numerically but I get an error

"unable to convert to an explicit first-order system".

Please have a look and guide me through the problem.

Thanks

Hi, I am creating a plot to demonstrate symmetry about the y=x axis, and I want to show that the line segment connecting two points is the perpedicular bisector of the line y=x. I have plotted y=x, the two points, and the line segment connecting those two points. How do I plot the perpendicular symbol (or right angle symbol) that is connected to the lines and shows that they are indeed perpendicular?

Let A(2 , -2 , 0) B( 4 , 2 , 5 ) & C( -1 , -3 , 0).Find  H(x,y,z) be the orthocentre of the triangle ABC.

Hello, everyone.

How to plot 

plot(-(2*(e-1))*exp(-3*x)/exp(-3)+(3*e-2)*exp(-3*x)*x/exp(-3)) 

this function is the answer of ODE: 

ode1c := diff(f(x), x, x)+6*(diff(f(x), x))+9*f(x)

ics := f(1) = exp(1), (D(f))(1) = -2

I got a warnning : "

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct
