My code consists of some execution groups. There are also some Text sequencies in between.

Now I've to calculate the whole thing with some differnet values so it would be great to be able to call a loop beyond the execution groups.

That of course doesn't work.

So is there any trick to execute parts of the whole sheet several times with different values?

can someone give help or a hint on how to overcome the faulty result in the pdsolve problem with radiation bc described in the following worksheet? I tried also with different method, but no success. the result from pdsolve makes physical no sense, because under pure radiation bc (h=0) the body should cool down and not heat up!

thanks :-)

btw, the problem was reported befor, see:

Hi, I am new to Maple, and, though I have scoured the internet and Maple's help, I have been unable to find a way to construct an element of F[x], where F is a finite field. Just to clarify, I am looking to construct a polynomial with variable x (eventually it will be multivariate, but I think I can extend to that easily), with coefficients from some finite field of size p^k, p and k being given.

I have seen a few examples online of people converting polynomials to...

Hi all

I am trying to draw a 3d plot from the data that I have created in excel, how do I import from excel to maple and then draw the 3d plot using array?

below is the link to my dataset in excel

Book1.xls

your help is appreciated

How I can say that an object,say k, is a constant(it may be positive or negative) inside assume()?

assume(k::??should I say)

pls also tell me what kind of help pages I should see for this kind of "type inside assume()" problems. 

Thanks.

I copied a column of figures from Excel and pasted them into an Maple worksheet.  Maple displayed a column vector with the appropriate values.  I set the variable y equal to this vector and was able to verify that, for example, y[3] had the correct value.  However, when I tried to use y[i] after a summation symbol which used i as the index I got the error message "Error, bad index into vector".  The summation expression worked fine when I redefined y by the following:

Hi to all

I am trying to merge two functions into a single graph. I have discovered the "piecewise" function but however I want to be able to manipulate the variables in both functions and plot a 3D graph to determine the results.

this is what I have so far

Z := proc (t)

if subs(p = 25, (100-p)*(1-exp((-1)*.11*t))/(10.00000000*exp((-1)*.11*t)+1)) < CM and 0 < t then subs(p = 25, (100-p)*(1-exp((-1)*.11*t))/(10.00000000*exp((-1)*.11*t)+1))

My question is very easy I have  and I want   how could I ask this to maple?

In particular my expression is 

How do I slection input and output in a Maple procedure?

Hi, I am currently trying to draw a standard airfoil NACA 4412 (http://en.wikipedia.org/wiki/NACA_airfoil). I've put all the equations and defined the parameters.

I don't know what is the problem, probably many Float undefined errors... According to me, it should be simple, but somehow I can't get it right. Any suggestions?

Thanks

Here is the file :  

I have 2 equations that are made up of various powers of 2 different variables. Is there any command to retain only terms of the first order? E.g. no "x^2", "x^{3/2}", etc, just "x"s.

I want to solve a series of differential equations, and then plot the results, but I'm having a bit of trouble with evaluating them using dsolve. My code is:

-----------------------------------

restart;

c:=1;
mu:=0.3;
m1:=1-mu;
m2:=mu;
x1:=mu;
x2:=mu-1;
omega1:=1/2(mu(1-mu)-3);
omega:=1+omega1/c^2;
r1:=sqrt((x(t)-x1)^2+y(t)^2);
r2:=sqrt((x(t)-x2)^2+y(t)^2);
A:=diff(y(t),t)*x(t)-diff(x(t),t)*y(t);
rsquared:=x(t)^2+y(t)^2;

Hi,

I'm trying to solve a nonlinear diff. equation numerically using (dsolve) but it gives me an

Error, (in dsolve/numeric/bvp) initial Newton iteration is not converging

my code is:

ode:= diff(f(x),x,x,x)+f(x)*diff(f(x),x,x)+B(1-(diff(f(x),x))^2=0   # f'''+f*f''+B(1-(f')2)=0

bcs:= f(0)=0,diff(f(x),x)(0)=0,diff(f(x),x)(5)=1                            # f(0)=0, f'(0)=0,f'(5)=1

Hi,

I'm using solve and I want all the solutions within a certain value, but then within my procedure i'm looking to get a list of just the solutions by using the AllSolutions=true command I get:

a:=evalf(solve([sin(x) = 0.5, 0 < x, x < 10], x, AllSolutions=true,Explicit=true));
 {x = 0.5235987758}, {x = 6.806784084}, {x = 2.617993879}, {x = 8.901179187}

I then need to put them into a list [0.5235987758, 6.806784084,...]

so i either...
