## Shifted Data IVP...

Hello everybody,

I just realised Maple is allowed for my upcoming exam after New Year.

My plan is to have templates of the most common math problems, I might encounter for quick solutions.

Anyway, I have run into a problem with Laplace shifted data, particularly initial value problems. I have been searching for HOURS, and feel like I have look up everything on google, maplesoft and other sites without succes.

I hope some of you are able to help me. The exercise is:

## Implicitplot3d bounded portion of surface...

I want to graph the portion of the plane 2x + 3y + z = 6 that are located in the first octant of a xyz coordinate system. The following implicitplot3d should in principle do it:

## How do I expand f(x,V(g(x))) in terms of x?...

I have a collection of functions defined either in terms of a single variable - call it r - or in terms of (r and) the other functions of r.

To be more specific, there are two free functions B(r) and N(r), a function theta defined in terms of N(r) and B(r) (and their derivatives) and r, and a free function V(theta).

Finally I have a function, call it f, written in terms of B(r) and N(r) (and their derivatives), r, and V(theta) and its derivatives with respect to both theta and r.

I'm creating a table of random math problems for my daughter to print out.  How do I get more columns?

a := rand(1 .. 15):
b := ["+", "-", "x", "/"]:

for i to 15 do
print(cat(a(),b[rand(1..nops(b))()],a(),"_____")):
print(``):
end do;

## Change to 1-D math (math input) with command in in...

I've made exam questions for students that they have to answer by doing some calculations in Maple.

I would like to let them copy the commands they used to a Maple TA text field.

However, the standard worksheet in our computer lab uses 2-D math. Copying this 2-D math to Maple TA works fine with "paste as plain text", but copying 1-D math also works with ctrl-v in Maple TA, which is more convenient for students under stress.

Since I am not allowed change...

## comparing expressions in expanded and factorized f...

Hi I teach in a high school. Basically I have found that if I ask a question like: Factorize fully (x4-y4), and use a MathContainer for both the question and the answer (to be filled by students), I can't find a way to see whether the students have fully factorized the expression. Suppose (x4-y4) is in MathContainer1 and MathContainer2 is to be filled in by students. Using the code:

if GetProperty('MathContainer1','expression'...

## Enter the solution of differential equations...

Hello Everybody.

Im new to Maple, so i have a couple of questions. In the last few days I have learned the basic of Maple, and now i would like to solve an differential equation.

The Math question is:

Enter the solution of differential equation:

In the link i have put in the informations from the math question.

## 2d Math - Numerical integer with index...

HI,

at first I have to admit, that I'm totaly new to maple and have only few experience with the programm.

That's the problem. I've got an old maple-code which I want to rewrite in the 2d-Math-syntax. In the code there are a lot of variables of the type "numerical integer" with a form like

"rho_a"

"N_A"

....

--> with index in the name

It's a code for a physical-/chemical- process so the...

## bifurcation diagram help...

It is the mathematica code for bifurcation diagram of the model that i am working with now. is there anybody who can translate it into maple code? or does anyone can help me with making a bifurcation diagram for such a ODE system in maple??

## Great Expectations

Maple

I've submitted an application to the Application Center: Great Expectations.  This is an interactive Maple document, suitable for instructional use in an undergraduate course in Probability.  The mathematical content is related to the Laws of Large Numbers and Central
Limit Theorem.  It requires no knowledge of Maple to use.

## Newton's Method in Maple...

Hello,

I'm doing a math assignment for numerical methods and I had to answer a question - solving Newton's method in maple to submit. I need to solve the question to an accuracy of 10^-5. I don't have access to the software right now as I only have it on the computers at our school, but I did take a maple course in my first year of university and have some experience with it. I wrote up this formula, but I'm not 100% sure if its correct. Could someone...

## Splitting nested sums into a set of single sums...

Hello,

I have a derivation to do for my PhD thesis, and it is long and tedious. It is essentially a case of splitting sums, making substitutions and then simplifying. I believe maple can do this for me, but have not found how yet. Any suggestions would be more than welcome. I have done this for a third order problem (three nested sums) and the derivation runs to many pages. I now need to do so for the 4th order problem, and it is a more than daunting prospect

## Problems finding the inverse of an algebraic 12x12...

Hello mathematicians :)

I have a problem finding the inverse of the following 12x12 matrix:

C:=Matrix([

[ 1, x1, y1,    x1^2, x1*y1, y1^2,      x1^3,    x1^2*y1, x1*y1^2,   y1^3,      x1^3*y1,   x1*y1^3],
[ 0,  0,  1,       0,    x1, 2*y1,         0,      ...

## Update math component...

Good Afternoon.

I have a problem with that project, because the when i move the dial (DialKp1) the component Mathbase don´t update the lat change.

I don´t know how can i do for updating it?
