Hi,

How can I create a help file in maple for a user function ?

Thanks

How do I get rid of the right-hand pallete dock ?

Hello,

 

this problem has been bugging me for months. I am defining functions with "if" in their definition.  These functions seem to be well defined, without any problem. Then I do sum and something goes wrong.  I have tried to isolate the problem to give you an example:

 

Hello, I am new to Maple, and I have a novice question on rounding with evalf function.

 

I have an expression:

m:=(x,y)->126*cos(a)^2*(cos(x)-sin(x)*cos(y+b+c)*tan(a))-42;

 

Then I set some parameters as constants:

g:=x->x*Pi/180;

a:=g(58); b:=g(-45); c:=g(100);

 

Hi Friends,

 

May I know How do I solve numerical differntial equation in MAPLE 12..?

My equation is very big..please send your valuable suggestion

 

Thanks

Is it possiobe til split a function into multiple varriables? I have seen something like this is a maple function "tools->assistants->backsolver".

Does anyone have a clue how thats done? I need it to my dynamic function ^^

Hi,

How can I write a command that the Maple assigns the numerical solutions of the dsolve command in a procedure such as the simple following procedure?

Maple solves the 4 equations for the 4 unknown, although I eventually need to end up with just the real part. Maybe I am doing something wrong. Once I get to the bottom of this worksheet and begin to try to extract (ie copy) each A1, A2, B1, B2, it freezes, my system stops functioning, to the point where I have to shut it down and restart it. Trying a few times, I see that, once I load this worksheet in, and begin at restart, once it does the last calculation, if I right click

Maple generates the values (numbers) for axis labeling automatically, e. g. 3.5   10E-3 for 3.5 meters. If I want to label the axis manually with millimeters, how can I fit the automatically generated numers to the manual given unit?

Assume n is positive integer.

dsolve((1-x^2)*(diff(y(x), x, x))-2*x*(diff(y(x), x))+(n*(1+n)-n^2/(1-x^2))*y(x), y(x))

Maple says

y(x) = _C1*LegendreP(n, n, x)+_C2*LegendreQ(n, n, x)

However

 dsolve((1-x^2)*(diff(y(x), x, x))-2*x*(diff(y(x), x))+(n*(1+n)-n^2/(1-x^2))*y(x), y(x), 'formal_solution', 'coeffs' = 'mhypergeom')

Maple says

y(x) = _C1*(Sum((-1)^(2*_n1)*GAMMA(_n1-(1/2)*n)*x^(2*_n1)/GAMMA(_n1+1), _n1 = 0 .. infinity))/GAMMA(-(1/2)*n)

I want to do an animation where the "Axis Limits" change during the animation.

Can I do that with Maple? how?

Thanks,

Sebastián.

Is there somewhere in maple where I can find a list of math, physics, engineering formula's?

I'm actually a little surprised maple doesn't have a math formula, physics formula, engineering formula etc...  help pages or something.  Just a list of formulas, like the cosine law, maxwells equations, bernoulis principle etc... or even simple formulas.  That one could reference to. 

It should be fairly easy thing to make, no? 

 

The Maplesoft office is currently in the process of being burried in snow and many of us are getting ready to head off for the holidays.  Before leaving, I wanted to share this great animated GIF created using 3d plots.  It was sent to me by Bruce Char at Drexel University. The greeting and the Maple script to generate it are after the break.

Hi All,

I was wondering if anybody could help me figure out how to find the closed form solution to a PDE, specifically the consolidation equation: dq/dz=C*d/dz(dq/dz).  I have a set of BCs but that is unimportant for now.

I would like the solution as a fourier series, but i'm new to maple and am not sure how to do this.  If anybody has a file set up to obtain the fourier series solution for a PDE and could post it, that would be a big help.

Thanks.
