I have this function : r(theta) = sec[t(theta)] = sec * (theta - (Pi/2) * (2/Pi *(theta + Pi/4))).

Since this function is in terms of (theta,r(theta)) ... how would I graph this in terms of Cartesian Co-ordinates instead of Polar ? 

Hi, I have animated plot visualizing the moving of point from location a to location b. I need line to be plotted in trace of moved point in area. Please see the code that I implement below. Many Thanks

L:=[[0],[34,7],[39,8,6], [45,2,3,7]]:
animate(( PointPlot, [L[trunc(t)]], t=1..3, frames=50), symbol=solidcircle,symbolsize=40);

Sorry for this simple question but I am new to Maple and need to do just this one thing...

Lets say I have a function fp(x) which draws out some envelope when I change p. I wanted to calculate this euqation by hand but this does not seem possible, since f is too complex. How can I use Maple to find the area under any Enevelope? Or maybe a bit simpler: How can I just find the envelope and save it to use it later?

I am sorry,since I don't know anything about Maple and I need that fast...

I want to solve the following equation and, assuming x=x_r+Ix_i where x_r and x_i are real and imaginary part of x,  plot x_r and x_i versus y . How can I do in Maple?



I have number 0.12

I use convert(0.12,string), result ".12" lost 0. Why?

Please help me @acer

Hi everyone
I am a learner using the maple program and I have a problem drawing multiple lines with different styles. I have tried the following:

restart; with(VectorCalculus); with(LinearAlgebra); with(DEtools);
F0 := 0; zeta := .25; w := 1; Omega := 1; m := 1;

ode1 := diff(x(t), t) = y(t); ode2 := diff(y(t), t) = F0*cos(Omega*t)/m-2*zeta*w*y(t)-w^2*x(t);

DEplot([ode1, ode2], [x(t), y(t)], t = 0 .. 10, x = -100 .. 100, y = -100 .. 100, [[x(0) = 0, y(0) = 50], [x(0) = 9, y(0) = 25], [x(0) = 85, y(0) = 20], [x(0) = .25, y(0) = .5], [x(0) = 7, y(0) = 5]], linestyle = [dash, dashdot, dot, longdash, spacedash], linecolor = [red, green, black, navy, maroon], thickness = 2, axes = normal, labels = [x(t), y(t)], arrows = medium, stepsize = 0.1e-1);

I would like to obtain in the graph that each trajectory has a different type of line.

On the other hand I wonder: Is it possible to use the options boxed and normal at the same time?

Greetings and thank you all

The above worksheet contains some computations I needed for a paper I am writing for the next issue of Maple Transactions.  The computations are within reach of hand computation (which is why I know the right answers).  I wanted Maple to be able to do them, however.

I couldn't make Maple do anything but verify that I was right (this is useful, I will admit).  But can anyone find any artful ways to simplify or solve any of those steps?  I suspect that this is quite hard in general, but with these things involving phi = (1+sqrt(5))/2 it's likely that others would find some "art" useful.  By the way, phi is not built-in to Maple, as far as I know.  Any more votes for including it?

There is an undocumented feature reported here that is useful: asympt works with "leadterm" and this turns out to be necessary.  I forget how I found out that leadterm works with asympt.  It's not in ?asympt, though I think that it should be.


This worksheet creates geodesics in the Poincare disk by transformation of a series of circles of diminishing radii in the complex plane.

The intersections of the geodesics are meant to create the first few pentagonal uniform tilings in the Poincare disk.

I do not know the mathematically correct way to create such a display, so the radii of the circles are only a trial and error approximation.

What Maple code will provide the radii of the complex circles which produce an accurate uniform pentagonal tiling?

Is there a better overall strategy for producing uniform tilings of the Poincare disk?


I have been trying to create a hyperlink to a bookmark in a maple document. I left the Target field blank, and entered the 

book mark in the book mark field. But I keep getting the error: " target cannot be blanK" Can anyone help ?


For this assignment ... I have to basically find the right 'road' and 'wheel' and then animate my findings. 

Problem is I am having a hard time understanding my professor's derivations of equations to find these roads and wheels. 

Here is the PDF for the assignment : square_wheel.pdf

All help is appreciated.



When I use Solve for a PDE with the option singsol=all, is Maple guaranteeing that I am getting all the solutions, and in partidcular , is it returning the *general* solution(s)? 

I have the following equations which I want to plot the curves of them by maple's:

1. |x+2|+|y|=3

2. |y|-|x|=2.

How to implement this task in maple?




How to insert captions fig.1,fig.2,fig.3,fig.4 in the Tabulate command ( variable G) without taking into account the random order of the graphs


Dear all
Dear all, is  there any Maple code available to solve the heat  two dimensional heat equations using Rk4. The second derivative will be replaced using Finite difference, so that we get a linear system of odes.  
Thank you for any help
