I am trying to export the animated gif generated by this maple code: It exports the animated gif with a gray background. How can I get a white background? Thanks

Hello all, I have a question about numerical integration in Maple. I have an equation (a PDF) which I need a numerical answer from as Maple can't find a closed form solution (which isn't too surprising given the equation in question). Anyway, the equation has several parameters which are varied and the equation looped over. That's no problem, and generally Maple will find a numerical solution to the problem. However, towards the extreme value case I get error messages basically saying Maple hasn't found a numerical result. The equation giving the error is: -20.01782577 I exp(-490.0000000 - 50. x) (-0.1625801243 10^212 I + erf(0.2258769757 I (9801. + 980. x)^1/2 - 0.2258769757 I)) dx

I cannot install MapleTA 2.51 with SUSE 10.1. It gives the same errors as I see in the forum for Maple 10. The suggested fix for installing Maple 10, commenting out the "export LD..." line, only leads to a new install error. It says that a ".Z" file is not a gzip file. Has anyone installed MapleTA 2.51 on SUSE 10.1 successfully?

I have Maple worksheets a.mws and b.mws in directory C:\maplecode. I’ve set this directory to be the current directory by executing the command currentdir(“C:\\maplecode

Hi, I have a proc that generates a "piston" plot in 2-D. I generate this with a procedure. Calling the procedure works, but calling it from Plot3d doesn't. I'm really not sure why. I'd appreciate the help. My stuff is below: Diameter := 46; Shape := proc (x,y) if((x^2+y^2)^(0.5) <>

hello, i just started using maple in school and i was wondering if i can make it show all calculations. it always gives a nice answer but im wondering it if can show me all step by step and not just the answer so it will help me learning. thanks in advance.

btw i tried looking in the manual and using google, but didnt find anything.

I have an expression of the form diff(var_name(t),t)= -K + procedure_name(var_name(t)) where K is a constant. The procedure is a boolean function. the var_name(t) is not recognised as a numerical value in the procedure and an error is reported. Any suggestions greatly recieved. The actual procedure is shown below. > restart: > m:=1: > P:=10: > RLLS:=proc(vt) > local max,v,N,k,feq,mu,lambda; > max:=.01: > v:=vt: > N:=9.807: > k:=.0001: > feq:=10: > mu:=2: > if abs(feq/mu*N)

Hi all. Is it possible to construct a generic polynom of degree n with generic coefficients a1 a2 .. an ? I would like to be able to write things like Sum(a_i X^i, i=1..n) in all generality. How to specify the coefficients (lists, arrays .. what ? ) ? Afterwards, the goal would be to be able to get the numerator and denominator of a sum of rational fractions indexed somehow by i plus a set of very generic coefficients a_i. Any hint of how to do this kind of manipulation is most welcome, even in the simple case where we are given the value of n from the beginning. Thank you for your attention.

I wish to extract the coefficients associated with a particular variable. I have assigned the results of a symbolic solve of a system of equations (sol) using assign(sol): One of the assigned variables in (sol) is ROLL and the symbolic solution is of the form ROLL; 200*a*b^2*VAR1 + 3000*b*VAR2 + 1500*cos(c)*d*VAR1 . . . (the actual expression is hundreds of line long and each VAR is randomly distributed in the expression) How do I isolate the coefficients associated with a specific VAR eg for VAR1 I want to be able to make the assignment coefVAR1:=(200*a*b^2)+(1500*cos(c)*d)

I use to own a old Maple version 8.0 since the RedHat 6.0 days. I have been able to make it run till FC3 (with export LD_ASSUME_KERNEL=2.4.1 and with a new JRE). However, recently, I upgraded the system to FC5 (kernel 2.6.15) from FC3 (I did not try FC4) and Maple stopped working. I've used the "export LD_ASSUME_KERNEL=2.4.1". The error I get is : $ /opt/Maple8.0/bin/maple /bin/sh: error while loading shared libraries: libdl.so.2: cannot open shared object file: No such file or directory /opt/Maple8.0/bin/maple: line 162: /opt/Maple8.0//cmaple: No such file or directory A ldd on libdl.so.2 gives

Hi, I've been trying to label the columns of a column graph I created using the ColumnGraph command. But I just can't figure out how to do it. Any tips?

In structural engineering the y-axis direction in beam deflection calculations is reversed. A negetive deflection is an upward deflection. I need to plot the deflection. A simple reflect command will do part of the trick, but the tickmarks are not reflected. How do I reverse the y-axis direction so it will be negetive to positive from top to bottom? Thanks.

This is my first time using Maple - so I don't even know where to start... Hopefully I can make this clear... example problem: f(x) = 2.3x g(x) = ax^3+bx^2+cx+d h(x) = px^2+qx+r l(x) = kx^3+mx^2+nx+s I was able to find the correct syntax for Maple to calculate the first and second derivatives of the functions above. Now I have to write out a system of equations using the original functions and their derivatives...once I have the system of equations then I need Maple to solve for each variable...what is the proper syntax for all of that? Also, for Maple to calculate the derivative I used "diff(f(x),x)" and "diff(f(x),x$2)", so how do I get those derivatives into my system of equations?

Hello, Earlier this year I reached an impasse with Maple's numerical integration package over the need for a high-resolution (say 50 or more digits) evaluation of multiple integrals for a Bayesian statistics application. An integral such as sqrt(1.+4.852800000000*chi[2]^1411+5.887416960000*chi[1]^200+4.852800000000*chi[1]^100+5.887416960000*chi[2]^2822-21.48043392000*chi[1]^100*chi[2]^1411) over a rectangular range like chi[1]=0..0.9999,chi[2]=0..0.9999999 would return unevaluated. Infolevel[`evalf/int`] explained that the methods available in Maple would not return the required precision. But the problem persisted even when I swallowed my pride and settled for 12 digits of precision. Stuck as I am, I haven't even tried to present the problem to Maple in higher dimensions.

i'm curious if exist any possibility to make a procedure like

myproc:=proc(x,y)
.
.
.
endproc

and then assign to it a typesseting rule which display statement

myproc(x,y)

to

x (some symbol) y

thx for any advice...
