For describing intermediate steps when calculating a definite integral, often in textbooks or other literature people use a square bracket on the right of an equation with the lower and upper bounds of the integral as sub- and super-script to the right of the square bracket to mean that the equation should first have the upper bound substituted into the equation and then the lower bound should be substituted into the equation and the latter subtracted from the former.  Is there any way to write this in Maple in a way that is visually the same?  I don't see anything similar in the

Find the general solution for the differential equation

x"(t) - 4 x'(t) + 4 x(t) = t * exp(2*t)

Hi

To find the deflection of a bar under buckling I am trying to solve a set of 10 unknowns and 10 equations, with equations like this one:

eq3 := C1*cos(P^(1/2))+sin(P^(1/2))+5*C3+C4 = C5*cos(P^(1/2))+sin(P^(1/2))+5*C7+C8

(the complete file is included)

When I try to solve the system, Maple is able to evaluate all the C's but not P. That makes sense, because P will be a solution of a transcendental equation (something like tan(x)=x) as opposed to the the C's all being linearly dependant.

Hey guys,

  Now I'm encountering another problem. I'm trying to assign a[n] as:

a[1]=1

a[n]=a[n-1]+1/2^(n-1)

I tried the following:

a:=[1, seq(a[n-1]+1/2^(n-1),n=2..10);

The result is "Recursive error".

The problem is this is a good recursive. Maple seems to simply not recognize recursive input at all.

I tried another way:

a[1]:=1

a:=[seq(a[n-1]+1/2^(n-1),n=2..10);

Result is the same.

I tried another way

a[1]:=1

a[n]:=[seq(a[n-1]+1/2^(n-1),n=2..10]

There is a Mathematica package OrthogonalPolynomials by Milovanovic sketched in facta.junis.ni.ac.yu/mai/mai19/f19-017-036.pdf
( ~ 200 kb and 20 pages). Is anybody aware of something similar for Maple?

I'm trying to do some work with a large matrix. I was using with(linalg), but I need to use LinearAlgebra now. However, if I don't use the command "matrix" (lowercase m) then I get this as an output:

Hi there.

I am having a little bother plotting a phase portrait of the following system:

DEs := [diff(u(t),t)=-a*u(t)+v(t), diff(v(t),t)=u(t)^2/(1+u(t)^2)-v(t)];

where 'a' denotes any real number.  I am trying to draw the phase portrait but I have know initial conditions. 'a' must also be from -0.5..0.5.

Any hints/tips would be greatly appreciated.  Thanks.

I'm trying to solve these 3 equations with 3 unknows. Without the constants c1 and c2 there is a solution. Is the problem ill posed and do I need more boundaries? Or is there just no solution?

Hi

I need to evalaute the Lauricella function of type F_A  for arbitrary value of   n , say around 2 to 10 or so. I think maple does not provide the ready function for the same and its is restricted to single variable series. Is there any method for computing the Lauricella functions in maple?

Thanks for any help

Vish

where can i get a german language pack? is one available?

I recently got my copy of maple in the university, but i cant choose german as my language.

To make everything a little easier (cause im new to maple), i was trying to find a language pack.  I hope there is a pack for download anywhere.

Thanks for your help.

Hello there, I have a problem solving the differential equation based on decomposition method. There are 3 operator which is N, R, G and u. N=4, g=-77, R=79. Below is the procedure, and yet there is an error at the last end statement. Please help asap.

Why does a^(3/2)*(1/a)^(3/2) not return 1 in maple? Sorry for the basic question, I'm just not sure what I'm missing.

I'm supposed to use a CAS to integrate (4*v*(m/(2*Pi*k*T))^(3/2)*Pi*v^2)*exp(-m*v^2/(2*k*T)) for v from -infinity to infinity. I know the answer should be sqrt(8*k*t/(Pi*m)), but I can't seem to get Maple to evaluate the limit once it integrates the expression. Any help is greatly appreciated. Let me know if I need to provide more information, I'm a bit new to the forums :)

Hi

I found the roots of a polynomial t^6+t^3+1 by hand, now i want to see if these values in the form exp(a*I/(b*Pi)) satisfy the polynomial, how can i do this?

Hey all. I'm looking at trying to generate a complete list of all maps from the integer plane to itself that have a maximal coordinate change (plus or minus) of n. Basically, I devised two wave functions that travel componentwise around the 8*n points d_inf=n from the origin, and am trying to use them to list every single equivalent map with such a metric-distance, from a point (x,y). Listed here is my current code, the problem I have on execution is that the i terms evaluate to that name as opposed to the assigned value.
