Hello all,

I was wondering if the following thing is possible and how to do it:

I have an assignment, to teach about circles and its equations. What I want to do, is to create some sort of application, that get as input the radius and and the other two parameters of the general equation of a circle, and plots it.

Now, to plot a circle using Maple 17, is fairly easy. But how do I create a graphical bar or other alternative...

LegendreP(m-1/2, l+1/2, coth(x))/sqrt(sinh(x))

I want to calculate the series about x=0 but I get the error 

Error, (in MultiSeries:-multiseries) need to determine the sign of, 2*m

What problem does maple encounter here?

I tried assume(m>0) and then I got the error

Error, (in MultiSeries:-multiseries) need to determine the sign of, 1-2*m

Is it possible to use printf to get math 2d output? For example, I'm writing a loop computing Riemann Sums.

f := x-> x^2; a := 0; b := 1; for i from 1 to 5 do printf("f(x[%d])=%a",i,f(a+i*(b-a)/5)*(b-a)/5); end do;

I would like the output to look nicer. Thanks in advance!

We are a school with more than 600 Maple users, we have 3 Mac mashines, different types that all give us the same problem. 

When installationi problems occur we use this method.

Restart MAC computer

uninstall JAVA

Restart MAC

get new version of Java - and install.

Restart MAC

get MAPLE 17 from homepage and install. 

We get a grey window where we can see next, but nothing else.

All users have adminstrative...

I was trying to get the labels and titles in a plot to be typeset using LaTeX fonts on a computer running SUSE 12.2.  Everything worked on a Windows 7 computer with the LaTeX fonts installed.  Maple 17 would use not use the CMU Open Type fonts that were installed on the Linux computer.  After switching in the CMU True Type fonts for the CMU Open Type fonts, everything works properly in the attached worksheet on the Linux machine.

I executed a Jacobian function as follows X:=Jacobian([a,b,c,d,e],[y[1],y[2],y[3],y[4],y[5]])
a,b,c,d,e are initialized expressions/equations and
y[i], i=1..5 are the variables and I got the result below

Hello all,

As in title I am really bothered with result in floating number obtained from laplace(expr, t, s).

I have a target to laplace and the laplace() gives me result with floating numbers.

(ex. laplace(diff(diff(f(t),t), t), t, s) = laplace(s^2. * laplace(f(t), t, s) : the period after 2 is annoying)

How can I avoid or do some conversions to kill the periods?

When I do integration and differentiation, even of the simplest functions, it gives me incorrect answers. What could I have done wrong? Just to mention I recently installed a licensed copy on my computer. 

Hi everybody,

Like the title said, I have a DC circuit (*.msim attach here).  In two differents ways, I find the current in R3 to be equal to -1A (*.mw attach here).  The M17 file is in french but the equations speak for themselfs.  Can someone help me to sort this problem out.

Thank you in advance for your help.

I am trying to use the procedure described in the answers to this question: 

http://www.mapleprimes.com/questions/100137-Solving-Trigonometric-Equations-For

to find the solutions to sin(2*x) = 1/2 where -2*Pi <= x <= 2*Pi. After the isolve() command is issued, I get the warning that solutions may have been lost. i think the issue is the form in which Maple represents the general solution to the equation. Any ideas on how to rectify this would be greatly appreciated!

I have a maple document with a few dozen plots. I am using the code

plotsetup(ps,plotoutput="C:\\plot.eps"); plot(x^2,x=-1..1); plotsetup(window);

to save the plot as an eps file. Is it possible to alter this code to save the file as a pdf? I've tried changing ps to pdf, but this doesn't seem to work. Thanks!

Is it possible to print an asterisk in a superscript? For example, the plot

plot(x^2,x=-1..1,tickmarks=[[1/2=x^*],[1='a']]);

has  at the tickmark x=1/2, but I'd like it to be x^*. 

Thanks!

Is it possible for tickmarks to be different colors? For example, say I'm working with the plot

plot(x^2,x=-1..1,tickmarks=[[-1,-1/2,1/2,1],[]]);

Is there a way to make the tickmarks at x=-1/2,1/2 red while making the tickmarks at x=-1,1 blue?

Or, alternatively, is there a way to turn the tickmarks at x=-1/2,1/2 into red subticks and make the tickmarks at x=-1,1 blue?

Thanks!

Hello,

I seem to be having trouble with the define_external command.

I want to call a C-library from maple, and I think I need to convert the maple data in C. So I need a custom wrapper.

But I can't get the simple example from here to work for me. Specifically, I tried this:

I am having trouble getting an algebraic solution for a first order four-ODE system. The problem seems trivial to me. However, Maple is taking a very long time to solve it. The system describes a reversible "chemical" reaction that have 4 states. Basically, the system is

C1<->C2<->C3<->O1

where the rate constants are ai towards the right and bi towards the left.

Any suggestion will do.

Thanks!
