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

With Regards

What is the value of u1 in this u substitution to go from -2*Pi*(int(sqrt(-3*u^2+4), u = 1 .. 0)) to -2*Pi*(int((4/3)*sqrt(3)*cos(u1)^2, u1 = (1/3)*Pi .. 0))? I'm just not seeing it.

 

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? 

 

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.

I want to prove by Maple if  -1<x<1 and n is positive integer then

sum(k^n*x^k, k = 1 .. infinity) = (sum([sum((-1)^(m+1)*(binomial(n+1, m-1))(r-m+1)^n, m = 1 .. r)]*x^r, r = 1 .. n))/(1-x)^(n+1)

I would appreciate for any help.

Dear all:

    I am wondering if there is any way in Maple to add properties to elementary functions? For example, both

is(sin(x),continuous) assuming x::real;

and

is(sin(x),monotonic) assuming x>0 and x<Pi/2;

fail. More specifically, how to tell Maple that sin(x) is continuous and monotonic if  k*Pi <= x <= k*Pi + Pi/2 ?

Another question is that I am not very sure how to use the monotonic property, i.e how it can be used to simplify your expression? Can someone give me an example?

Thanks,

1. How do I take a 2xN matrix and plot it on a 2D graph by its columns?

2.How do I take a number n and a 2xN matrix and return the product of A^n with the 2xN matrix, where A is a 2x2 matrix?

3.How do I, using your two functions above, write a procedure which plots on the same graph the result of multiplying the 2xN matrix by A^n for n = 0,1,2..10. How do i cause these sequence of plots to be displayed as an animation?
