ramivei — Sat, 14 Apr 2012 20:37:19 Z

Hello,

I wish to enter in the math dot operator but I can't find the way to enter it in the document mod. I also searched the help and did not find a way.

all I want is to enter dot(varphi)

thanks

create math page exercises to print for my daughter

Christopher2222 — Tue, 27 Mar 2012 14:13:52 Z

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;

Express algebraic expressions as a single fraction

Yew Hong — Mon, 26 Mar 2012 08:23:26 Z

Hi all, I found that the expression:

(2x+7)/5+(6x-3)/3

automatically simplifies to

Is there a function that will return

which is one fraction, instead?

Change to 1-D math (math input) with command in initialisation file

Petra Heijnen — Mon, 30 Jan 2012 14:24:28 Z

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 forms

Yew Hong — Mon, 26 Dec 2011 04:26:45 Z

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'...

2d Math - Numerical integer with index

Xilyte — Tue, 13 Dec 2011 05:49:20 Z

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...

Newton's Method in Maple

AbuGabu — Mon, 31 Oct 2011 16:32:41 Z

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

jimbo_cambridge — Mon, 17 Oct 2011 15:43:42 Z

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

Hello mathematicians :)

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

C:=Matrix([

Update math component

Jorgenecochea — Wed, 29 Jun 2011 18:26:15 Z

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?
