hi, for example i have this equation:

i need to factorise it so that i have all of the eta^2*g^2 terms together, can somebody pls show me.

 

thank you

 

Hello there.

I´m fairly new to maple, so i apologize if this is a rather "simple" question, but right now I don´t really know how to get rid of the error message that occurs.

What I try to do is define 3 components of (in this case) a function that describes a magnetic field. These functions ( seen below) depend on a few parameters (a,b,c,d,p and chi).

restart:

I'm attempting to plot a Laguerre-Gaussian beam in Maple. I have u(r, theta, z)=f(r, theta, z). What do I need to do to it to make it plot properly? I've tried to equate it to something, but it claims it is not in parametric form. What does that even mean?

Hi

I am trying to plot E as a function of t for a following implicit integral equation:

(int(sqrt((1-(1-E^2)*(sin(x))^2)/(1-(1-E^2)*t^2*(sin(x))^2)),x=0..pi/2))=0

I am using implicitplot, but apparently it loops until infinity and not give any answer.

I tried also to change the integral boundaries to x=0.1..1.55 with no result.

 

I'll appreciate any help

I've bought a new computer recently and was disappointed, because Maple uses only 25% of that processor (my old computer used 99% of CPU).

I have Intel Core i5 750 processor (it has 4 kernels).
From the Screenshot you can see that It uses only 25%, but not because it uses only one kernel (it uses all 4 kernels).

If I open two Maple instances and run the same program on all of them at once then I get 50% of CPU used.

The question is:
how to force to use Multi-Kernel processor to work at 90% (if needed) with one single Maple program?

It seems that this isn't a limitation to Maple, but for all other programs as well.
For example,

hi, maple wont solve this...

L=1:  seq([fsolve(cos(beta*L)cosh(beta*L)-1=0,beta)],n=1..6);

 

can anyone pls offer some insight into this.

 

Thanks

if i have a saved single plot without any programing codes, how is possible to add a verical text for it's vertical axis label?

why isn't possible to copy a whole plot in maple 13 and paste it in another locationof that page or another new blank tab, whereas in maple 12 was possible!?

Hello, I was wondering if someone could help me with the following problem. I have a procedure AAP:=proc(A, titel) local a,b,c,d; a:=A; b:=[solve(t^3-a=0,a)]; c:= (z-L[1])*(z-op(2,L))*(z-op(3,L)): plot3d(pol(0), dsc(2), hsv( carg(F),1,1),ori,nweb,grid=[100,100], title=titel) end proc: for j from 1 to 8 do AAP(j,Figure j+1) end do;

Hi,

I am trying to reuse a function that I computed numerically (using dsolve).

My dsolve line is something like this

Sys:=dsolve({f1(0)=0,diff(f1(x),x)=...},{f1(x)},numeric}

Then I want to define a new function as follows:

g(x):=2*f1(x/2) and use it in solving another ODE system.

How can I do that?

I could solve the ODE only numerically.

Thank you.

the equation is like the pic below:

int(sqrt(1+16*a^2*y^6+24*a*y^5*b+16*a*y^4*c+8*a*y^3*d+9*b^2*y^4+12*b*y^3*c+6*b*y^2*d+4*c^2*y^2+4*c*y*d+d^2), y = 0 .. .2)

i try it by Maple ..but did not get any answer of it ! anyone can help me with this ??or there is no real answer for it ?

since the equation got 4 unknown constants which are a,b,c,d ...so how to use maple to solve it ???

any idea and comment will be much appreciated ...thx

Hi all,

I have a relatively simple question that you can do by hand, but I want to know, if it is possible for MAPLE to compute directly with a single command if any 2 vector functions do intersect.

eg. r(t) = <cos t, sin 2t, exp(t)> s(t) = <sin t, cos t, exp(t)> ,  -2 < t < 2

thanks in advance
