I'm working on solving the basic 1D, transient heat transfer equation in a two layer slab configuration.  One side is insulated, the other has a constant heat flux, and there is not contact resistance between the two layers.
 

Hi everybody!

I am working with Maple 11.  I want to animate the trajectory of a body in free-falling.  I got almost everything but there is one more thing I want to animate and I can't find out what's the problem?  You will get in the following link the file I am working on and more clearer informations.  Thanks for any help!

Hello all,

I've been trying to add a legend to a graph in Maple 11 but have been having no luck. Here's what I tried:

plot({z, ff(z), fr(z)}, z = 0 .. 1, legend = {front, rear, ideal});

This gives me the following error:

Error, (in plot) the legend option cannot be used when plotting a set of objects

After looking in the help file I tried plotting this, which works:

plot([ff, fr], 0 .. 1, legend = [front, rear]);

Hi to everyone I'm Marco from Italy, I'm new in this forum and I've  Maple 9.

I've to use a "do while cycle", but i don't know how to do it

This is the problem: T(i+1)=T(i) + f[T(i)] until {abs[T(i+1) - T(i)]}/T(i)<0,001

can someone help me to write the correct line commands?thanx ; )

Hi, I have a pretty long symbolic expression and want to make Maple not output the function arguments in derivatives. I also want to make it print the derivatives of function of one variable as primes not D's.

For example lets take a function of one variable f()  with argument which is combination of two variables (x+y) and evaluate the partial derivative

diff(f(x+y), x);

I don't want Maple to print the argument of f() after the derivative and I want it to print the derivative of f with respect to its argument as prime not as D.

How do I solve this system?

2x + z(2x-6) = 0

2y + 2yz       = 0

x-6x + y = -23

these mixed variables and terms confuse me.

OK I thought this would be very easy, but after much puzzling I still can not figure this out.

Let's say that I start with some explicit floating-point numbers:

a_num := 1.330 :
b_num := 2.440 :
c_num := 3.660 :

The I construct a function using these values:

func := ( a_num + b_num * x ) * exp( - c_num * x ) :

Now what I need to do is simply the opposite of this: given the function func, and given an explicit known form of the function, assign the values a, b, c. Hypothetically it would look something like this:

Hi!

I'ld like to know how is implemented the proc "lagrange" in Maple (I mean which is the followed algorithm when you call it), and in general how to get access, if possible, to the way any proc (already implemented in Maple) is implemented.

Waiting for your help,

thank you.

Hi again.

Hi

Suppose I do the following definite integral:

Int(cos(m*x)*sin(n*x),x=0..Pi) assuming m::integer,n::integer

I recieve

-(2*m+2*(-1)^(1+m+n)*m)/(2*(-m^2+n^2))

Since I don't want to be mistaken wiht the first minus sign I do

collect(I1, m, normal)

Is there a way to tell Maple that m+n is odd or even since the answer depand on this information.  Of course, in this case, we can see immediatly but just for the peace of mind.

I am attempting to intergate with maple, also using Vecotr Cal. notations and have come upon some errors.  Maple tells me it is unable to match deliminators.  What does that mean?  I am new to using Maple and lost in it.

Thanks,

I used rand() to get a list of random numbers between 0 and 1. It gives me something like

[.30000000, .50000000, .20000000]

But I want this to be like [.3,.5,.2]. As my code tells that both the above lists are unequal !!! How ? kindly explain me.

regards,

Athar
