I WAS WONDERING IF ANYONE COULD HELP ME OUT... I DOWNLOADED A STRUCTURAL MECHANICS PACKAGE THE OTHER DAY FROM THE MAPLE APPLICATION PAGE.... I KNOW I CAN RUN EACH OF THE DOCUMENTS INDIVIDUALLY BUT I DON'T KNOW HOW TO CALL THEM UP IN THE PROGRAM.. CAN ANYONE GIVE ME STEP BY STEP INSTRUCTIONS OF HOW I CAN INSTALL THE PACKAGE IN MAPLE 13..

THANKS IN ADVANCE!!!

Hi,

I have purchased an e-book for Maple called "Advanced Engineering Mathematics". I have found it to be full of red code text (which I understand to be 1-D Maple format, correct?).

Is there a way of converting the contents of my e-book to get rid of this red text (or at least convert it to something more meaningful) ?

Thanks and regards,

I would like to ask a 2-part question in Maple TA in which the correct response to the second part of the question is based on the student's response to the first part of the question.

Here is a simple example.

Question #1

A) What is 1+4 ?

B) What is 2 times your solution to part A?

Obviously, the correct answer to B is 10, but what if the student thought that the correct answer to A was 4? Then if they put 8 as the answer to B I would...

When I write

evalf(Pi);

I get  3.14159...

But, when I want to visualize the value  "e", after writing 

evalf(e);

I get       e .

Why I cannot see the digits of "e"?

Did I instal not properly my Matlab14.0?

Hi,

Just a simple question:

How do I unassume (remove the assume) all the variables in my code in the easiest way?

Thanks a lot for your help.

In a loop (variables set to some calculation) when maple produces an error how can I set it to a value of zero?

I want to find the first positive and first negative root of a bessel function

j2 := (x, a) -> k(x)^2*a^2*(diff((diff(1000000000*sin(1/1000000000*k(x)*a)/(k(x)*a), x))/(k(x)*a), x))/(k(x)*a)

I couldn't use the built in bessel function with two variables, so I had to enter it by hand.

I want to find the values of x where j2 is zero as a function of a:

f := (a) -> RootOf(j2(x, a), x, 0 .. 2)

plot(f(a), a = 2 .. 2.25, y = -3 .. 3)

Hey folks. I have a massively complicated equation I'm trying to solve and the internal memory can't take it.

Here is the problem.

Let f(x) := 1 - lambda*x^2

alpha := 1/f(1)

By solving the following equation,

alpha*f(f(x/alpha)) = f(x) + O(x^4)

We can determine a value of lambda and hence alpha (for which the real value is roughly -2.5 and the calculated value here is roughly -2.7).

hello everybody

please heeeelp

Hi

I have a question about releasing a part of memory occupied by some lists, sequences and matrices, for example matrix "M" or list "L".

If we use the following commands to allocate amount of memory for a matrix or list:

M:=Matrix(2000,2000,float[8]);
L:=[seq(equ[i],i=1..10000)]:

where equ[i...

hello everybody can you help me please

how can i canvert this list [1,2,3,4,5,6] to a number 123456

hi ,friends

  now ,i get a matrix of symbolic expression,it's difficulty to find the simplest forms using the common command  as like simplify or combine

p := Matrix(4, 4, {(1, 1) = (1/2)*exp((1/2)*J[1]-(1/2)*J[2]+(1/2)*J[3])+(1/2)*exp(-(1/2)*J[1]+(1/2)*J[2]+(1/2)*J[3]), (1, 2) = 0, (1, 3) = 0, (1, 4) = (1/2)*exp((1/2)*J[1]-(1/2)*J[2]+(1/2)*J[3])-(1/2)*exp(-(1/2)*J[1]+(1/2)*J[2]+(1/2)*J[3]), (2, 1) = 0, (2, 2) = (1/2)*exp(-(1/2)*J[1...

Hello friends,

When I solve the optimization problem with restriction (below):

NLPSolve( ln(x1) +ln(x2+5), {x1 +x2 <=4}, assume = nonnegative);
     [-Float(infinity),

       [x1 = HFloat(0.0), x2 = HFloat(0.8333333333333334)]]

I get the expression  "-Float(infinity)"..

What do Float(infinity) and  HFloat(0.833333) mean?

Thanks for the attention,

Hello everybody!

I'm working on a statistical problem. I need to plot confidence regions for parameters in the model, but I don't know what I should do. I tried to get some programs from the internet, but either they don't work or I don't understand details of them to change for my work. Can someone introduce a good program to me?, or does anyone have another useful idea for me?

Thanks a lot!

I meet a problem in the use physcis package.
