Hi,

Is there some way i can label the x axis with numbers and an 'a'? I want to make an infinite square well of width 'a' so i'd like to keep the central zero and put an 'a' and '-a' on the x axis on either side of the origin.

So far i have this:

restart;

a:=1;

for n from 1 by 2 to 3

Hello, I have tried to solve a system of ODE about the gyroscope for a week. I have entered the following commands : >eq1:=(l^2+r^2/2)*(sin(theta(t))^2*diff(diff(psi(t),t),t)+2*diff(psi(t),t)*diff(theta(t),t)*cos(theta(t)))-r^2*(cos(theta(t))*diff(psi(t),t)+omega(t))*diff(theta(t),t)=0;>eq2:=(l^2+r^2/2)*(diff(diff(theta(t),t),t)-(diff(psi(t),t))^2*sin(theta(t))*cos(theta(t)))+r^2*(diff(psi(t),t)*cos(theta(t))+omega(t))*diff(psi(t),t)*sin(theta(t))=g*l*sin(theta(t)); >eq3:=diff(diff(psi(t...

Thanks for the answer.

As I have maple 9 I was not able to read the adjusted file you attached (plots were not available). But after implementing the changes you suggested (changing the order in proc (m, lambda) and adjusting the numpoints), i still get the same combined plot with the restricted area being larger that the general function :(.

Best regards, Olga

I am an engineering student working with maple. I'm currently working on a large worksheet with lots of sections. I would like to be able to prevent maple from expanding (sub)sections when calculating commands within them when I re-execute the whole sheet and I would not like to comment them out. Is this possible?

I have searched this forum before, but to no avail, who can help me.

Thank you in Advance!

I want to produce the matrix representation for the symmetric group.

I have the 3 generator matrices for

(12),(13),(14) but I am having trouble producing the complete set of 24 matrices with no repeats.

I would like some kind of algorithmic process as I would like to produce the S5 and A4 groups later.

many thank for any help

I want to know for what combinations of parameters (x,y) the following holds: Prob(X(x) + Y(y) < z) = alpha. X and Y are random variables (I want to look at different distributions), z and alpha are constants. I tried the following (simplified with X=Y):

HI

Can anyone help me.

I would like to use the combin package using Maple 12. The question is how can I generate the letters of the alphbet (26 letters) choosing only 3 combinations which must include the letter "A" 

any help would be appreciated

Please explain details of the fmt string in the mapleta function numfmt.  The help page only says

Returns the value of x, formatted according to the template fmt.

 For example,

 numfmt("#.00", 20.9)

Hi!

Problem: How can I prevent Maple from checking against the simplification table?

Eg.

I enter

f := 5 y z x + 3 x^2;

and 5zyx + 3x^2 is returned.

Then I enter

g := 3 x^2 + 5 x y z;

and again 5zyx + 3 x^2 is returned, but not wanted, because I wanted to have a different (visual) representation of the polynomial.

How can I prevent this? Or how can I delete the first representation from the simplification...

Dear Sir / Madam,

Would you recommend me how to isolate the real and imaginary part and simplify the equation A? Maple cannot evaluate this equation to numeric value...

A := evalf(sqrt((Re(B))^2 + (Im(B))^2));
A := evalf(abs(B));

are not working.

I have attached my equation function.txt

I will include the work i did, also near the end of the worksheet, there are word descriptions of the questions i did.

Im stuck on the last 3 questions: question 14, 15 and 16. I cant seem to find the values i need for my Ce^-kx

I tried diff it but my syntax is preventing me from going farther.

All help will be appreciated! i will include the original lab for more clarification!

f(x)=(sin@@3)(0.5143600172e-2+1.000000039*arcsin(arcsin(sin(sin(-0.1543083839e-1+.9999999610*RootOf((sin@@3)(_Z)-(sin@@3)(0.5143619410e-2+1.000000000*RootOf(-(sin@@3)(_Z)+x))))))))

i want to find inverse of this funtion i am getting nothing

>s := solve(w = f(x), x)

    s:=

i am getting like above.

i want to find inverse of above function plz give me reply to me.

I finished this lab for my Differental equations class today. The computer I was using is not linked to a printer. I saved it and went to open it on a differnet compter and I got an error saying there are problems with the loading process.  I tried reopening it on the computer I started with and I get the same error

The lab has three parts. The first two parts were part of the the professors instructions and introduction. Those parts load up. The third part is...

With f := i->`if`(i = 0, 1, alpha), I'd like to evaluate expression A below entirely symbolically, i.e. with l=1..3 being replaced with l=1..h in

sum('sum(sum(f(i)*f(i+j), i = 0 .. l-1), j = 1 .. h-l)', l = 1 .. 3); subs(alpha = .3, h = 3, %);#A

but using  A with l= 1 .. h provides a different number, the one one obtains with

sum(sum(sum(f(i)*f(i+j), i = 0 .. l-1), j = 1 .. h-l), l = 1 .. h); subs(alpha = .3, h = 3, %); #B

Expressions...
