MaplePrimes Questions

In a loop I want an output similar to this 

1x, 2x, 3x, 4x, 5x

So here's some code to get a sense of what I was trying to do

for i from 1 to 5 do
  `#mscripts(mi("x"),none(),none(),none(),none(),none(),mn(i))`;
end do;

Any ideas?

I was writing problems about the bisection method and decided to use the Maple routine Student[NumericalAnalysis][Bisection].  The problem I wrote generates a cubic with all three roots in a somewhat random interval.  Students are then asked to find a root to a given accuracy using the bisection method.  If one does not hit a root, the Student[NumericalAnalysis][Bisection] routine gives the desired answer.

A problem arises when the bisection algorithm...

1. I have a Matrix V as following, and I found that Determinant(V,method=float) can not work. I use Maple12. Please help me , thanks.

2. also, in some calculations, I found Determinant(V,method=float) and Determinant(V,method=minor) gave different result. Anyone can tell me why?And which method is right?

V=[[0.2412702414,0.4868267037+4.770943828 10^(-17) I,-0.3582351644-3.597026404 10^(-14) I,0.8897131421,0.3035225208,0.2809455226],[0.5973344699,-1.205280722,1.019534434+1.083003890 10^(-16...

In a cup run and CuI crystals PbCl2. Did four works of solubility: pKCuI = 11.96, pKCuCl = 6.73, pKPbCl2 = 4.29, pKPbI2 = 8.19. You have 4 unknown concentrations in the solution, but 5 equations (which?). Can you explain what will happen? Documented with calculations.

Recently I was looking at an algorithm in one of Knuth's books.

The algorithm is described in steps with many of the form 

if condition 1 then goto step 7; if condition 2 go to step 8, 

etc.

I managed to write up the algorithm by making each step

a procedure, but had trouble with handling global variables.

 

Is there in Maple some standard method for dealing with such algorithms.

A friend tells me...

Hey,

I've been running the following program in a maple worksheet and it has worked fine.

Now I want to run it on an Ubuntu machine that has some extra computing power to get through a big data set.

However I get strange "Incomplete Quoted Name" errors, even when I have no quoted names in my input at all.

This is just alittle bit of the output I'm getting:

I'm seeing strange behavior when I try to numerically solve the heat equation with radiative boundary conditions (heat flux proportional to 4th power of surface temperature).  I set up a simple example of a plate that sees 300K on one side and 310K on the other.  Two obvious flaws in the solution of the radiative example are that the slope of the curve always has the wrong sign at the left boundary (sometimes wrong on both boundaries), and that the solution runs away...

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).
