Forgive me for not using the "Maple Math" and "Maple Plot" commands.  I tried, but it says everything that I enter is an invalid expression so I'm just entering it as text...

I define two functions, they plot as expected:

f(x) := sin(x);

g(x) := 2*x;

plot( f(x) );

plot( g(x) );

Now I want to plot the composition:

plot( f(g(x)) ); 

Doesn't work!

Preliminaries:

• Not processing matrics, vectors, or equations (as members).
• Decided sequence Data Structure for an element addressable DS, is most liking to my needs.

Task at Hand:

• Processing integers consecutive from 1 to 10,000 (later upto one million) for multiple properties.
• Presumed marking of a memeber to indicate T/F.
• (later) Although, in time, to perhaps? place a sequence inside that member, for additional degrees of marking, or "bigger data" too.
• Example: bag_list[ 3] := 1; BL[5] 1, 7 1, 11 1, 13 1, 17 19 23 ...
• ie, Marking the primes.

Dear All,

I am not an expert in Mapple, also my calculus courses were quite long ago. I would like to compare different decision methods. The simpler ones worked with the code below (even if it was slow). but I have problems with the differentiation and the integration of two complex methods (i.e., dia and topsis).

All these methods can be described in general with the  following function:

f:= (X::Matrix,C::Vector)-> TerminalScores::Vector

Hi There,

I'm having a problem trying to solve the folllowing system of PDEs.

PDE1:=diff(P[e](x, t), t) = 5e(-5)*diff(P[e](x, t), x, x));

PDE2:= diff(P[s](x, t), t) = 5e(-10)*(diff(P[s](x, t), x, x));

IBC:={5e-5*(D[1](P[e]))(0.2e-3, t) = 5*10^(-10)*(D[1](P[s]))(0.2e-3, t), P[e](0, t) = 1, P[e](x, 0) = 0.1e-1, P[s](0.215e-3, t) = 0};

Sol:= pdsolve({PDE1,PDE2},IBC,[P[e](x,t),P[s](x,t),numeric);

Error, (in pdsolve/numeric...

I would like to combine a maple 2d-plot with a existing jpg-file in one graph.

How can I do that?
I tried something with ImageTools, but that doesn't seem to work.

Hi at all. In my attachment you will see my problem. I want to fit datapoints with a set curve and I used the Fit-command. If I plot the points and fitting curve the curve is not on the points. Where is the false in my sheet?

I used "implicitplot"  and get the plot. But I want know the data of the plot. How to get the data?

I have downloaded and unzipped a student version of Maple 14. When I click on the icon named Maple14MacInstaller.app, it flashes and nothing happens. What now?

Mac w OS X, 10.4.6, 3.06 GHz Intel Duo with 4GB RAM.

I'm not sure if this might be stretching Maple's capabilities a bit, but I was wondering if there was a way to perform model reduction (through substitution) in Maple?

Let me explain. Suppose I have a system of nonlinear equations: f(y,z,u) = 0, where u = input variables, z = intermediate variables, and y = output variables. For instance:

y = z1 + z2^2

z1 = z2 + 3*exp(u)

Hi,

I have been looking for "creating a folder"-option in my group in Maplecloud. Is this possible at all or can I really only have an hierarchy depth of one?

Best regards,

Since Maple 14 requires a new version of the license manager (which isn't downwards compatible for some reason..), I'm currently trying to figure out how to run two versions of maplelmg on the same Linux host, one for Maple versions 13 and below, one for 14 (and above).

Of course, this would have to happen either on different ports or another IP on the same host, which doesn't really bother me, the problem is that I cannot start two maplelmg's on the same host because...

loop.mw

I want to use loop to get results for two satements with one counter

like this:

for i from 1 by 1 to 5 do Y_i :=i , X_i :=i^2 end do

but maple shows this error unterminated loop

I need to use some statements in one loop and I separated them by comma but maple gives error

What should I do?

  Dear all, I am using fsolve to solve a complex equation. When I solve it, I get the following error:

Error number of equations, 1, does not match number of variables, 2.

But the variables are just one (named u1) I think it is a problem with assume but I am getting cracy to understand the problem.You can find in attachment the short maple file. I try to solve equation e4 for variable u1.

thanks
Alberto

the integral
>int(1/x^2-cot(x)/x,x=0..infinity,CauchyPrincipalValue);
with Maple ?
Stars predict it equals Pi/2. Maple 13 easily cracks the integral
>int(tan(x)/x,x=0..infinity,CauchyPrincipalValue)=Pi/2.
