Hi friends

This is strange for me, but Maple could not solve the below integral. I tried with online version

of Mathematica and it solved for me. The solution is Hypergeometry function. 

> f := ((1/2)*r+1/r)^(1/n);

> int(f, r);

What is the problem?

Regards!

I want to be able to create expressions in the two noncommutative variables a and b such that an expression

(b+a)*a +ba symplifies to a*a. Thus the first expression expands to ba+aa, which when added to ba

yields ba+aa+ba=aa.

How to arrange for this will be greatly appreciated.

Hi, I would like to label curves on a plot but using horizontal text looks really bad.  I would like to use verical text labels or even text labels that follow the curves.  It this possible in Maple?  I have tried rotate with textplot but that only rotates the point and not the text.  Any ideas would be great! Thanks.

Hi,

Is there any syntax highlighting for the "code edit region"?

thanks.

please in nead help in this aaplication (HydraulicsStewartPl) :

1-How  do i change the position of platform in playback mode ?

Hi!

I'm wondering how to substitute  in the equation below with

I want solve this inequations

> solve((1/4*(beta^2-6))*(-beta^2+2*alpha) > 0);

After running, maple gives an answer in four lines

alpha < (1/2)*beta^2     0 < -(1/2)*beta^2+3
(1/2)*beta^2 < alpha     -(1/2)*beta^2 < -3
[]                                 beta = -sqrt(6)
[]                                 beta = sqrt(6)

now I have questions:

1) In spite of knowing range of beta in thhe second parts of first two lines of answer, why maple...

Hi,

I have two Sum as:

f:=t->Sum(A[m]*cos(m*w*t+m*t0),m=0..mm);

g:=phi->Sum(B[n]*cos(n*phi+n*phi0),n=0..nn);

I want to get the product of f*g as

h:=(t,phi)->Sum(Sum(C[m,n]*cos(m*w*t+n*phi+cmn),n=0..nn),m=0..mm);

Is it possible and how to do that ?

Thanks

A simple timing program

st:=time():
for i to 35 do
  i;
end do;
time()-st;

On M16 seems to display after 7 seconds, the time reads 0.010
On M12 it displays in roughly 2 seconds with the time as 0.170

It is physically longer with M16.  Do others get the same results?

**edit add**
No comments?  I should add that it is a laptop 1.4Ghz single core.  Not that it matters but maybe M16 is set up to work more efficiently...

Hello,

I am trying to read some text filw with maple. But the first few lines in this file are nothing I need to read. Do you have any Idea how to skip? If I use readdata I get some lines from header too, because there are some numbers.

So text looks like:

.............................................................................
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
........................................................................ ...

I simplified the real task and

the principal problem is how to assign a condition( if x < 3 then t := 0 elif x >= 3 then t := 5 end if) to a variable t which depends on x (x is a argument of function g(x))?

Is it possible at all without writing the procedure?

Here is the code:

g := proc (x) options operator, arrow; 2*x+t end proc; if x < 3 then t := 0 elif x >= 3 then t := 5 end if; plot(g(x))

Hi, may I know how do I change only the diagonal to certain values please? Thank you.

with(LinearAlgebra):
M:=RandomMatrix(6):
G:=DiagonalMatrix(RandomVector(6)):

Question 1: How do I change the diagonal part to a certain value for example 'a'?
Question 2: How do I change the diagonal part to the vector G?

Hi, I have a statement and when b is greater than 3, I would like two outputs which are z and y. But I can't seem to have it working. Please help. Thanks.

a:=2:b:=4:c:=7:d:=2:

this is what i wrote:
if b>3 then z:=a and y:=c elif b<3 then z:=d and y:=a end if:

Hi, may I know what is the function "ismember" in matlab called in maple please? Thanks.
