Lab5.pdf

Im currently doing number 1 right now on this lab which i attached, and i cant seem to think of a function that suites that description, im going to ask my instructor for more clarification, but i was wondering if anyone could give me some suggestions on how i could come up with the one needed

Thanks!

How do I convert K1*cos(w*t+theta1) + K2*sin(w*t+theta2) to a single K3*sin(w*t+theta3). Maple keeps simplifying to the cos + sin form but that is not user friendly for the signal viewed on the oscilloscope. The conversion is easy to do with a calculator but I want to automate the process in Maple with parameters so I do not have to copy and paste expressions or type them.

Thanks for your help,

Can any one help me??

I would like to use permutations choosing only 3 letters of the alphabet with "A" in the permutation.

eg) (a,a,a) (a,a,b).................................(z,z,a) etc

Can any one help me, I would appreciate any help

I'm trying to make an infinite square well of width a, and i want to plot individual solutions along with the walls of the well at x=a and x=-a, does anyone know how to modify my code to show the solution and the vertical lines at x=a and x=-a, id like to also show that the wavefunction is zero at the walls, but due to the equation it continues past them, is there some way i can either modify the equation to stop the plot at x=a and -a (preferable) or blank out the graph after the walls?

Hi

I entered this code :

> printlevel := 2:

> for i to 3 do for j to 3 do i*j end do end do;

but it does not show the result

what should I do?

thx

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...
