It's obvious how to use Maple 10 for creating a document, but has anyone used Maple 10 for presentations? I'm going to present in a seminar in a couple of weeks and have some Maple demonstrations and graphics to show the group. I'd be interested in hearing tips, suggestions, experiences and ideas for presenting mathematical content to a group from within Maple. (I'm familair of course, with Powerpoint and LaTeX slides, and the LaTeX Prosper package. I'd use LaTeX/Prosper except that then I have to embed the Maple in the presentation. It would be more convenient if I can use Maple solely.)

Dear All, First of all thank alec and Prof Doug. Please refer to post http://beta.mapleprimes.com/node/362#comment-729 My problem is to solve the following ODE with constrain given by the Eq: > DEq := diff(f(x),x) = c1*sqrt( g(f(x)) - g(f(x=x1)) ); > Eq := ug - f(x=0) = c2*sqrt( g(f(x=0)) - g(f(x=x1)) ); > g(f(x)) := exp(f(x)-xn) +exp(-f(x)) +(1-exp(-xn))*f(x); where ug is the independent variable and others are parameters > c1 :=-257753830.552993398770016153893; > c2 :=1.40376701562707174099362643812; > xn := 35.4196679725860384893589519100; > x0 := 0; > ug := 40; I have tried to followed alec's suggestion but the solution sometime still cannot be obtained. The independent variable ug has to be varied from -50 or less to + 100 or more. The intial guess in solving f0 (f0 := fsolve(g('fx0'(f0))-gfx0(f0),f0=30);) has to be input manually, this is a big drawback.

In the third line of this do loop is the assignment assigning both the null set and the new value of the index into the original null set ? Also does this mean that the final set S contain the original null set with multiple null sets nested in it ? >

What does "Warning, `delta_Ia_con_p` is implicitly declared local to procedure `inductor_current_RMS_AVG_p`" exactly mean?

I get this, when I execute the following procedure:

# art=0 returns RMS current and art=1 returns AVG current
> inductor_current_RMS_AVG_p:=proc(Ue,Ua,Ia,L,T,art)
>
> delta_Ia_con_p:=(Ue-Ua)/L*Ua/Ue*T;
> inititial_inductor_current_con_p:=Ia-delta_Ia_con_p/2;
> initial_inductor_current_p:=piecewise(Ia<eval(IaLG_boundary_condition), 0, inititial_inductor_current_con_p);
> # initial_inductor_current_input:=initial_inductor_current;
> inductor_current_increase_p:=initial_inductor_current_p+(Ue-Ua)/L*t;

i put system of eqn to dsolve (3) sol := dsolve([sysode, icsode]); and i am getting sol:= is it means that maple can't solve it?

i have a function f(q(t),...)= q(t)*sin(q(t)). i need to do df/dq(t). how? thank's

how do i count the numbers of elements inside of a list like [[x,y,z]]? ie. [[3,2,5],[2,34,6]]. i would want it to return 2.

Why do I get the same output with the two following statements plot3d(0, 0..20, 0..70, color=proc(x,y) 200000*x end proc); plot3d(0, 0..20, 0..70, color=proc(x,y) x end proc); How does the option "color=proc() ..end;" works? How can I choose the colors? (The reason behind my question is that I am trying understand how to plot the Mandelbrot set)

i have a list in the form of [[x,y,z]] where x,y,z are integers, i want to find all the elements of the form [0,y,z]. how do i do that?

This is a screenshot of what I get when I open Maple 10 http://img226.imageshack.us/img226/5010/maple100fe.jpg (copy and paste url) The Maple Calculator also results in the same problem What Java programs are required for Maple 10? I have the Microsoft Virtual Machine installed as well as Microsoft SDK 4.0. I am running XP with SP2. Any help is greatly appreciated.

Why am I getting a false statement as output for this input ? > >

hi i am mechanical eng. student. i am new user of maple and i am useing maple 8. i need to do symbolic diff, diff of theta is theta dot. theta is function of t but i don't know it. i am building a def. eqn. with Lagrange equations. how i do it with maple?

I have a module with an exported procedure defined by define_external, like this:

loadtest := module()
export hb;
option package;
hb:=define_external(
`hb`,
`MAPLE`,
`LIB`="/home/hans/system/maple/libhb.so");
end module:

This works if I put the code above into a .mpl file, and use read to load it. The problem is that I would like to save this module to a maple library:

> libname;
"/home/hans/system/maple", "/usr/local/maple8/lib"
> savelibname:="/home/hans/system/maple/loadtest.lib":
> march('create',savelibname,100);
> savelib('loadtest');
> map( march, [ 'gc', 'reindex', 'pack' ], savelibname ):

When I try to use this newly created library after restarting maple the following happens:

> A:=Matrix([[3,2,1,-2,-1,-4],[1,0,1,0,-1,0]]):
> with(loadtest);
[hb]
> hb(A);

		[	3 2 1 -2 -1 -4	]
	CALL_EXTERNAL(	[		]	)
		[	1 0 1 0 -1 0	]

Hi everybody, in Maple 9.5 I need to generate two Vectors of random generated numbers from a normal distribution with a certain correlation. The correlation should be an input factor. Does anyone know how to do that?
