As many of the users on MaplePrimes are instructors, I thought it appropriate to let everyone know about a new resource available on the Maplesoft web site called the Teacher Resource Center.

Hello,

when using Maple to do simple calculus I usually have to explicitly state the dependence of each variable in the expression....for example

c*(1-cos(x[1](t)))+x[2](t)^2/2

is there a way to declare generic functions of a dependent variable say

x1 = x1(t) or x2 = x2(x,y,z)

and avoid having to do it repeatedly in an expression? I know i can use subs to replace patterns, but can you declare somthing like f(x,y,z,t) without giving the details?

Thank you

I seems that Maple doesn't know anything about the convexity of functions. It would be nice to have a command to check the convexity of (real) functions in Maple, also Maple should have knowledge on the convexity of known functions: for example: constant function, linear function , abs, sin (convex on a specific region) etc. To deal with the calculus of convex functions: for example Maple should know such theorems: if f(x) and g(x) are convex functions and g(x) is non-decreasing then g(f(x)) is convex, etc.

I just want to reiterate how dynamic programming problems can be solved in Maple. Especially dynamic programming models that frequently appears in economic models. First of all it is important to note that is close to impossible to find an easy to understand and step-by-step road maps to dynamic programming. Why is that ?! The below Maple code was basically "discovered" by trial and error and pure stubbornness (caveman 101).

In the field of calculus Maple is very strong , the strongest i have ever seen, but with work with algebra is very week i will say very poor. Equation manipulator works only with equation not with expression . Look how it works on Algebrator 4.2 and you wil see what I mean. Simplify doesn't work corect see example in atachment. If you have step by step solutions on integrals this to implement on algebra is 100 times easy becouse here you know what is the next step.

With expression palette for multivariable calculus in Maple entering multivariable calculations wll be very easy such as double and triple integrals, line and surface integrals. No other program such as Mathematica or Matlab have this, why Maple don't be first who has this option.

Sorry for my english it's not my mother language.

As a follow-up to the original post, I thought I’d mention a few of the additional new features particular to math education. For more information, visit the What’s New section of the website. Concept Learning Tools: Maple 13 includes new and improved concept learning tools:

The third edition of Getting Started with Maple was released by John Wiley & Sons in March 2009.

The author team for this edition is:

The 13-digit ISBN is 978-0-470-45554-8.

I have recently been working on a problem using fractional calculus and have come across something in Maple's fracdiff command that makes no sense to me.

Consider the function y:=a+b*(x-q)+c*(x-q)^2

z:=subs(x=q,fracdiff(y,x,1)) gives the correct answer of z:=b, z:=subs(x=q,fracdiff(y,x,2)) gives the correct answer of z:=2c, z:=subs(x=q,fracdiff(y,x,3/2)) gives the answer of z:=4*sqrt(q)*c/sqrt(pi)

I was hoping to give my calculus III students a short introduction to using vectors in Maple. I wanted a few simple things like plotting vectors in three space. I loaded VectorCalculus. Got the dot product and cross product to work, and I can plot one vector -- although it looks more like a telephone pole with a cap than a simple arrow. But despite all my attempts to give plotvector a list of vectors, I am completely unsuccessful. There has got to be a better way. I'm quite frustrated after searching through documentation for several hours. I'm cert

Dear all, Would appreciate some guidance for this question: If q = ax + by and r = bx - ay, determine the value of:

I'm an autodidact working with calculus and Maple 9.5, I find the Maple Learning Guide more illustrative than comprehensive and the help files too oriented toward users who know more math and/or more Maple than I do. This forum has proved helpful in responding to specific questions, but I'm looking for some books that would provide guidance on the full range of Maple's potential. I'm not looking for a primer, but rather something as comprehensive as the help files that makes fewer assumptions about the reader's knowledge and is written

Question: Being given the function f (x) =1/(3x+1),

a) By using the definition of the derived function (and not the rules of derivation), determine f' (x).

b) Determine the slope of the tangent to the curve of f (x) at the point (1, f (1)).

Instructions: You must use Maple 12 and show your calculations.

Thank you for the assistance offered with these forums.

If anyone can advise me about how to create the tool that I describe below, that would be great. I am a novice to Maple and object-oriented programming, but I can program in C and I suspect that I can write a Maplet, if that is indeed the best way to achieve my goal. This is what I want to do.

How does one do the indeterminate vector product with and Dyadic calculus operations with Maple 12?
