Hi

Is there any way to type maple code in an alternative editor and then run it directly in maple? I find the editor in maple a bit of a mess. Particularly the indents, I can only seem to indent by a very large tab and then if code spills over into the next line it starts at column 1 again making for very difficult to read code.

Any suggestions for either linking an alternative editor with maple or improving the indent situation in maple would be very useful.

Thanks

 

I want plot this abs error function

with two variable, I set

x:=-0..2;

plot(abs(sin(x*w)-cos(x*w),w=-2..2));

 

But it is not displsy. Why ,Can you tell me about how to

plot the figure.

1. How do I take a 2xN matrix and plot it on a 2D graph by its columns?

2.How do I take a number n and a 2xN matrix and return the product of A^n with the 2xN matrix, where A is a 2x2 matrix?

I installed Maple 12 under windows XP. The machine satisfies the hardware requirements given in the documentation. Activation was confirmed.

On startup, the welcome screen appears. After entering the document/worksheet window, it stalls. CPU usage is close to 100%. I waited about 30 mins and had to kill the application.

Maple classic and command line maple work fine.

On this machine I previously had Maple 11 installed, with the same problem.

I'm using maple 11, and I need help changing the axis variable to something other than x vs y.

For example, I want to graph  y= 1+x(2x^2 +3) ^ (1/2)

by changing the eq to ((y-1)/x)^2= 2x^2 +3

and plotting ((y-1)/x)^x  vs x^2 I can obtain a straight line.

How can I change the axis to this instead of  x vs. y

Obviously I'll be using with(plots, implicitplot);

 

I'd like to use the Del operator in the form (A.Del)B, where A and B are vector fields. In Cartesian coordinates this is (Ax d/dx + Ay d/dy + Az d/dz)(Bx ex + By ey + Bz ez), but in other coordinate systems (which are the ones I want to use) it's much more complicated. Is there a way to use the Del operator in this form? (ex, etc. are unit vectors)

Hi, I want to plot a set of complex numbers which have the property: |z-1|/|z+1| < 2

I should get a circle but plot() only uses real numbers.

How do I? ;)

Hi Friends,

 

How do I speciy X-Bar in Maple 12..?

Kindly tell me ,  I am new user to this.

Hi, I have a function which was derived from an integral. I want to find its inverse, or more importantly, plot ONLY the inverse of the function on the plane. Is there a command which allows me to execute such things? Thanks

==> Integral calculus and differential 1

Question: Being given the function f (x) =1/(3x+1),

a) By using the definition of the derived function (and not the rules of derivation), determine f' (x).

b) Determine the slope of the tangent to the curve of f (x) at the point (1, f (1)).

Instructions: You must use Maple 12 and show your calculations.

Thank you for the assistance offered with these forums.

Hello,I'm trying to solve system of 3 equations for a problem of using Larrange Multiplier

> e1 := 3*x^2+3*y-a*(2*x-6);
             
                          3 x  + 3 y - a (2 x - 6)
> e2 := 3*y^2+3*x-a*(2*y-6);

In order to prepar an exam, i would like to discuss about how virus spread.

I got some informations about different models, such as SI, SEI, SIR, MSEIR... and their differentiel equations

But i have some troubles to write and solve them.
i would like to use maple to modelize this propagations, but i don't know how to do at all.

Could someone give me a base, for a quite simple model such as the SI model?

Thanks

I have the following functional:

I am looking for the following: given Chebychev polynomials T up
to degree n I want to express them as Legendre polynomials P.

For example one can use OrthogonalSeries[ChangeBasis] for given n.

My question is: can one give/describe/generate/... the transform
matrix for the bases directly?

The intended use is for n <= 512 (or considerably smaller), the
special case T ---> P would be enough for me.

Certainly this is classical, but I can not find it out (or looking
it up).

For structural engineering problems, when I multiply a force (N) by a distance I generally want the answer in (Nmm) or (kNm) or units of that form.  Yet Maple simplifies the result to Joules, which doesn't mean a whole lot to me when I'm trying to find stresses and strains in structural members.

My question is, how can I define my own set of units that I'm comfortable with instead of having to accept the default Maple units?  I'm not having a lot of success customising units with Maple.
