When I open my file I get this message....What does it mean??? Why it appears?

 

 

 

I don't know if it's clear, but what I want is write a formula  ...And I'd like it to treat it as Text not math (I don't want Maple to execute it, of course appears an error message if so)

I looked over the FAQ's and I was not doing anything wrong according to them but I have tried graphing all of the following and got blank graphs as a result every time. I am using Maple 12 on Mac OSX Leopard 10.5.4. plot3d((2*x^2+y^2)*e^(1-x^2-y^2), x = -1 .. 1, y = -1 .. 1, axes = normal, scaling = constrained, numpoints = 10000) implicitplot3d((2*x^2+y^2)*e^(1-x^2-y^2), x = -10 .. 10, y = -10 .. 10, z = -10 .. 10, axes = normal, scaling = constrained) implicitplot3d((z = 2*x^2+y^2)*e^(1-x^2-y^2), x = -10 .. 10, y = -10 .. 10, z = -10 .. 10, axes = normal, scaling = constrained)

I need to be able to enter number line plots into MapleTA questions and answers; I have found no built-in functions to do so, and as such have created my own crude Maple function for drawing them piece by piece.  However, this function is a bit longer and uglier than I would like to see replicated in every single question that uses it, so I was hoping to have questions share this function between them, hopefully in the form of a module or library, eventually with a variety of such functions, which I can maintain in one central location.

I have a worksheet saved, but if I try to continue where I left off, Maple has forgotten what all the variables mean and what their values were. 

It's not like I have to retype everything - the commands are still there - but I have to press enter about a hundred times to reenforce what the meanings of all the variables were. 

Is there a way to save it in such a way that you don't lose such information?

This is what I ve to solve...It's simple!And it works, but if I write:

>fsolve({2*x + y = 1, x - y  = 2}, {x, y});

>y;

it writes y and to the value that solve the sistem!Did you understand?How can I do it?

 

>fsolve({2*x + y = 1, x - y  = 2}, {x, y});

I must say I am pretty dissapointed by the fact that TA4 still has a lot of very basic, obvious bugs and suboptimalities which I would have thought were clearly apparent in TA 3 and could surely have been corrected.   For example:

(1) $a=0;  $b=$a;     sets $b = -0

(2) $c=frac(-2,-1)     sets $c = --2

Hi,

I have the following (simplified here) formula:

G = ∫∫ g dp (n * dr)

The last part "(n*dr) is actually a dotproduct. How do I put this in Maple? Usually you use something like "G:=Int(Int(g dp (n), p=0..1), r=0..1) but than I don't have a dotproduct between "n" and "dr".

How do I build a cobweb plot of a recursion equation in Maple?

for example,if we have a table T=table([aa=2, bb=3 cc=4, dd=5]),how can we get another table(2=aa,3=bb,4=cc,5=dd) ?

another question:
if we have table([aa=3,bb=5,cc=1,dd=3]),how can we output indices according to entries' ascending order?

thank you

i would like to know any of you guys have any ideas on forecasting economy. basically using different equations and its command in Maple?

Is there a way to convert a complex expression into the form a + ib (splitting it into its Re and Im parts) , even if the expression that you want to convert is in terms of a variable?

ie, I have something like f(r) and I want to put it in the form a(r) + i b(r)

How do I set maple to work with this units kN (kilo newtons), MN (mega Newtons 1MN= 10^6 N)??'  I'm Just starting with maple. Thanks for your help!

Hi All,

Would anybody be able to explain to me how to find the steady state temperature distribution in maple using the finite difference method?

 

Any help wouild be greatly appreciated.

 

Cheers

Hi

I am getting the following error in Matlab for an equation that I converted from Maple using the Matlab() command.

"Subscript indices must either be real positive integers or logicals."

Maple does show this warning before giving the Matlab code.

"Warning, the function names {alphaD} are not recognized in the target language"

The equation is the derivative of a function with more than one variable.

Please help to sort this out.

Thanks
