## vertical lines ...

Hi Maple experts and others,

We want to make a graph with 6 vertical lines.  One end of every vertical line will be on the x axis.  The other end of the vertical lines will be on integers of data points.

## output to file of an ODE solution...

Hellow,I use maple 13 (linux)

How can I get a output data file solution of my ODE? For example, the maple resolved the harmonic equation and got a u(t) function, but I want manipulated the data in a external programm, like gnuplot ou xmgrace.

hello!

I'm new in Maple!!

I am try simulate the termal flux in composite material using heat equation and perfect contact between the materials. But I can't enter the fourier condiction and my code don't work!!

Any help??

Every time im working with maple and answer is in term of sin or cos maple dont calculate them for example it give me sin(pi/2) but i want it himself know that sin(pi/2)=1 some times i use of [eval] but it again dont calculate it what i should do?

While using the RKF45 in MAPLE to solve ODE w.r.t. time, analysis results came out without any information regarding a total number of iterations or a total number of time steps used in the actual analysis.

I would like to know how can this information be checked in the MAPLE.

Thank you very much.

## How do I search for integer coefficients?...

HI all,

Let all variables be integers here.

I am trying to search 3 variables , "A","B",and "C" so that f(A*x2+B*x+C) factors into two binomials.

Here, f(y) = y2+y+19.

Choose a search space of 0<A<10 and 0<B<30 and 0<C<100.

I am having some trouble with my Maple code.

Here is how far I got -
