Acer is a genus of trees and shrubs commonly known as maples. The genus is placed in the family Sapindaceae. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, Acer laurinum, extends to the Southern Hemisphere. The type species of the genus is the sycamore maple, Acer pseudoplatanus, the most common maple species in Europe. The maples usually have easily recognizable palmate leaves (Acer negundo is an exception) and distinctive winged fruits. The closest relatives of the maples are the horse chestnuts. Maple syrup is made from the sap of some maple species.

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...

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:

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:

\\
$$
It's not difficult to simplify...
