May I legally obtain a student license of Maple if I’m merely auditing a class? Need it be a STEM course? I tried google and Waterloo did not spell out the case of auditing.
How can I plot 'file1.dat 2nd column' vs 'file2.dat 1st column' in Gnuplot?

Hi!
I'm trying to solve ODE system with 2 equations
Here is a result from dsolve. How can i get R(t) out of it
And how to substitute initial conditions in it?
My context here is Finsler geometry with Cartan connection. I use ##x^\mu## for the usual spacetime position coordinates, and ##u^\mu \equiv \dot x^\mu## for velocity coordinates (the overdot denotes differentiation by an arbitrary parameter, not necessarily proper time). To explain the problem...

Please see attached image. I'm not sure why I'm getting this error because this is the format I have used to write programs in Maple before. Any ideas? I'm new to this so not sure how to independently trouble shoot or problem solve this,
Thanks!
I was just wondering how many of you had heard about the Math “programming” software called “Maple” and if so, what your opinion is on it compared to like Matlab or Mathematica and the other mainstream languages?
Is such a “low-key” software/language learning extensively?
I personally find it...
Hi all, I am new to the Maplesoft software and have been experiencing trouble computing numerical integrals.

Hi everybody.
I'm using the Maple 13 software (in linux mint) to solve system compounded by the four below differential equations:
> ode1 := (diff(m1(t), t)) = - m1(t) + (1/2)*tanh( m2(t) + m4(t) + cos(t) );
> ode2 := (diff(m2(t), t)) = - m2(t) + (1/2)*tanh( m1(t) + cos(t) );
> ode3 :=...
I have recently been doing some work that involves long, messy manipulations with lots of geometric series. A typical such series, which would only be one of a number of such terms in a formula, is:
$$
\sum_{t=h+1}^{T-h} \left(1-(1-\theta)^{T-t-h+1}\right)
\\
$$
It's not difficult to simplify...
I have been using Maple for sometime as its document interface feels nicer and more friendly than mathematica's . I have never been able to plot arrows in Mathematica or use indices efficiently. I am more of a curious self teaching physics person. But I just found something interesting when...
Hi,
I would like to know if is possible define a set rule explicitly.
