Maple is amazing at making secret codes.

First, let's learn two quick words. To "encrypt" a message means that you have transformed your message such that it is unreadable by others.

And to "decrypt" means to transform it back to your original message, also known as code breaking.

We will encrypt and decrypt our original message "Hello new Maple users !".

Hi...

What's happening is simple, I wrie in maple 3/2, press enter and maple shows 3/2 in the result, right click there....then Numeric Formatting, I choose Fixed (with 2 decimals) and maple changes the result

1,50 instead of 1.50.       

How can I change this???     Note: My windows is in Spanish but I have configured the dot as decimal point

Thanks a lot!!!

I don't know if th e Subject Explains my problem...

But I'll expalin

I have a vector column (44 rows), and I want to assign the first 22 rows to a another vector and storage it in a variable and the same with the other 22 rows. How can I achieve this???

By the way, with this same vector, when I print the page, maple "cuts" the vector and the whole vector is not printed, is there any way to solve this??

Thanks a lot!

Hi

I'm trying to work out how the Global Optimization Toolbox works and I thought I got it working. However, when I increase the ranges of the parameters over which the Toolbox should look for the solution (but still including the previous range), the outcome of the optimization changes, i.e. the toolbox finds different optimal parameter values and a different, and often higher, Sum of Squares (which is my evaluation criterium). I don't understand what I'm doing wrong!

An example:

No relation apparently.  Is there a computer algebra system with a nice snappy name that can actually be trademarked?

Hi All!

I have recently purchased Maple-12.0 (CD based) from the local reseller in India. While trying to install in my x86_64 laptop, it gives the following error

We still use MapleTA where we have begun using shared classes more.  Today I saw something which might have been visible before, but which I did not understand:

Hi all,

it seems to me that Maple is not able to simplify very simple equations, e.g. the one stored in "d" variable in the following example:

For increased flexibility, I have been using a system of one question per assignment. I allow students, say, three attempts at a given assignment. I cannot find a way to reduce the maximum mark available for attempts after the first. Does anyone know if this is possible? If not, is there a workaround? I did think of creating a 'copy' of the assignment for each attempot but the admin of this may get excessive. Many thanks in anticipation of your help.

Helloo

I'm trying to solve this large system (I attach it) for the variable eqn

It's a vector assigned to the variable and I don't know how!

Thanks  a lot!

Let's consider the function f(x)= tan(x)- x and its root in the interval (Pi/2,3*Pi/2)

Firstly, we zoom the intersection point of the function with g(x)= tan(x) and h(x)= x ( or the function f(x) and the Ox axis):

plot([tan(x),x], x= 4.3..4.55, gridlines=true);

 Now, we use the Newton-Raphson method to reach the root, like this:

Hi,

I've been working with Maple lately for my thesis, mainly running numeric solutions for my model.

I have a question regarding the loop command.
Using Fsolve I want to solve non-linear equations for several variables given some parameters. What I want to do is to plot the solved variables for changes in one of the parametrs.

for example, suppose I want to show, on 2 separate graphs, the oprimal (solved) variables of x and z, against  changes in the parameter y for these two equations:

If I have a function of R.  I want to find out if there is an R value for which the function is positive.

And if possible, what that R value is.  I graphed the function for a whole bunch of ranges of R values, but there's only so much I can do with graphing.

This is somewhat similar to command in  MATLAB "isreal(p)" which returns true if p is a real number and false if p is imaginary, but instead I want to know if the function is positive for ANY values of R. 

A string with a lead ball of mass m is slowly pulled upward through a small hole. Consider the work done on the system during this process. Find the change in energy and the frequency of this pendulum during this "adiabatic process", assuming the amplitude of the pendulum to be small.

Sorry I don't have a picture.

(Imagine the situation of the wire holding the chandalier in your home being slowly pulled up through a small hole through the roof while it is slowly oscillating in one dimension, or in a single plane.)
