# What is Maple: Definition and 266 Discussions

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.

33. ### Maple Fixing Maple PDE Error: pdsolve/numeric Expecting IBCs to be of Type {list, set}

I used the following code and got the error: Error, (in pdsolve) invalid input: pdsolve/numeric expects its 2nd argument, IBCs, to be of type {list, set}, but received IBC the code is: how to amend this error? Btw, the second boundary condition v_x(1,t) should be approximated by the...
34. ### Mathematica Mathematical software: Latex, Mathml, MathType, Maple?

Which mathematical software(s) can you recommend for 1. As a substitute for a calculator (TI89): making basic graphs, regressions (linear, exponential), vectors, solving equations, showing graphs in 2d and 3d? 2. Writing an ebook with lot's of math. I'm thinking Mathml or Mathtype might be...
35. ### Maple - Finding maximum of maximums in different functions

Hello, I've been trying to come up with a short way of writing the code. What I'm trying to do is: I have 11 equations, each of which have a defined minimum and maximum. I'm trying to find the highest maximum out of all of them and I need to know which one it is. The highest as in farthest...

Hi, I have the next expression: \frac{iw+3}{(iw-3)(iw+6)(iw+1)} Now I want to find the real part of this expression via mathematica or maple, and for the love of god it doesn't work, what have I done wrong here?! the codes and their errors are in the attachments...
43. ### Maple Calculating Time Derivatives of Terms with Autonomous Systems

Hi guys I have 5 term which each term includes three function of time (autonomous system ), i want to obtain time derivative of each term as other terms for example if i define each term as a dimensionless variable , e.g. x , y , z , v , w , i want to know dx/dt = as a combination of x , y ...
44. ### Maple How can I fit a sigmoid line to data points using Excel or Maple?

Hi I used plot digitizer software to pull data points off a picture of a graph and i need to fit a line to the points (and get an equation for the line). I know the data points fit to an s-curve from the picture. I'm thinking excel doesn't do this, or maybe I missed it? I have access to maple...
