So I came across the conversion ability in Maple 10 (My school had some trouble with the registry, it's fixed now, so we're up to date with 10!) Anyways, so I made it convert simple statements and functions, but now my question lies in exactly how deep can this conversion functionality go? Is it possible to say write a java program and convert it into a Maplet and vice versa? I know that Maplet doesn't exactly work like a full blown computer language as alec made clear in his post on the front page, but lets say I wanted to make a window in Maplet, can I convert that from Maplet to java and

for example sin(x) from 0..5Pi how would i count the roots? there obviously would be 6 roots but is there a maple command to count these for me? thanks

my computer is too slowly , its evaluating about 12 hours,but have no result. P4 512MB windows XPsp2 Maple 9.5 who have the strongest compter who can try to run it. (i guess maybe the procedure have some problem). View 1984_new equation with water out.mw on MapleNet or Download 1984_new equation with water out.mw

How to draw the graph of y=100+[sin(w+1)]^3 and the 1st two degrees?

with(Maplets[Elements]): maplet := Maplet([[Label(Image("E:\\image.jpg"))], [Button("OK", Shutdown())]] ): #Maplet 2 (creates the file that it will use to pass back parameters) #fd := FileTools[Text][Open](testFile, create=true, overwrite=true); MapleCalculator:=Maplet( # inserted ( [ ["Field 1", TextField['TF1'](10)] , ["Field 2", TextField['TF2'](10)] , [Button ("Calculate", Evaluate((TF3='TF1' + 'TF2')))] # inserted ) , ["Value: ", TextField['TF3'](10)] ]): # inserted ) Maplets[Display](maplet); Maplets[Display](MapleCalculator);

So I was messing around with Maple somemore, and I got the image idea to work, now my question is, is there a timer system for Maple? I have looked at the example that Maple 9 presents to me, but it's very... very complex for what I want. You see in the example it says to use the computer clock as a form of time, and this is technically possible by using -now() command (or something like that) to determine what the time was, what time it started, and then using that to determine when to set it off... though the details are a bit fuzzy now, it is still a rather extensive way of doing a simple thing.

i need to addition my equation like that,but this does not working. i try to use the >'add(add(add(x*y+y*z+z*x+a,x=x1),y=y1),z=z1);' but get the wrong answer, the 'a' addition 4-times. this is my original procedure: > x1:=[1,2,3,4,5,6,7,8,9]; x1 := [1, 2, 3, 4, 5, 6, 7, 8, 9] > y1:=[9,8,7,6,5,4,3,2,1]; y1 := [9, 8, 7, 6, 5, 4, 3, 2, 1] > z1=[4,5,6,3,2,1,9,8,7]; z1 = [4, 5, 6, 3, 2, 1, 9, 8, 7] > eq1:=add(x*y+y*z+z*x+a,{x=x1,y=y1,z=z1}); # 'a' is a const. Error, wrong number (or type) of parameters in function add

I've been trying to figure this out for the life of me and I keep getting an error somewhere. I'm trying to set it up so I have values for all four sides so I've used an array of variables to assign the values.. ie: [0,1] [1,1] [1,0] [0,0] but when i try and combine all of these in the plot, I get an error. Any help would greatly be apperciated. Thanks!

I'm currently in first year calculus, so my knowledge is limited, please forgive me. I've been given an assignment, and a part of it has me rather stumped (the teacher likes to give out questions before she teaches you how to do them). We are given 3 single-variable functions (domain is 0 <= x <= 40): h1 := x-> -5 * ( 1 - x^2 / 1600 ) * sin ( ( Pi * x ) / 1600 * ( x / 2 - 3 ) * ( x / 2 - 20 ) )^2; h2 := x-> -5 * ( 1 - x^2 / 1600 ) * sin ( ( Pi * x ) / 1600 * ( x / 2 - 6 ) * ( x / 2 - 20 ) )^2; h3 := x-> -5 * ( 1 - x^2 / 1600 ) * sin ( ( Pi * x ) / 1600 * ( x / 2 - 9 ) * ( x / 2 - 20 ) )^2;

Hi everybody, As a part of some general problem, I need to solve a system of non-linear ordinary differential equations.I try to get a numerical solution, so I use the "dsolve numeric" command. In same cases, the Maple print out two errors that I didn't find in his help instruction. The first one is: error, (in dsolve/numeric/bvp) cannot determine if this expression is true or false: 20*nerr

I am trying to get students to solve inequalities. They have to enter intervals and I modify their response-string before processing it. Something weird happens when using RegSubs. I have reduced the behaviour to the following maple*-code: expr := convert("$RESPONSE",string); with(StringTools); expr1:=RegSubs(",(.+)[)]"=",Open(\\1))",expr); evalb(expr1="(0,Open(1))"); This returns true when I enter "(0,25)" (without the quotes of course; you can replace 25 with anything you like). So, instead of the parenthesised .+, the \\1 just yields a 1. When I execute the code in my own Maple10, the correct substitution is made. I think our server runs Maple9. Any comment is appreciated.

Please see the message written by Douglas for the correct code.

g := x -> x^3+x^2-3*x; h := 0.01; x := 1; yaydone := (g(x+h)-g(x-h))/(2*(h)); OK, I did some poking through my book, and it shows how to solve for the first derivative using the Central Difference method, it actually took me quite a while to get this formula going. This will solve for the first derivative using the Central Difference Method. I didn’t understand the book at first and thought I was supposed to use The Derivative of g(1+h) minus The Derivative of g(1-h). This really had me boggled. So now I am able to solve for the first derivative using the Central Difference Method My question is how to solve for the second & third derivative. My book has no examples for solving for anything other than the first derivative. Thanks so much for the help guys, I truly do appreciate it and I truly hate the book that I got to learn from

hi it seems that i realy did not undersand modules in maple 10 so here I come with a few question... 1, is possible to use modules right as a objects like in c++? 2, i want to have an objects: point,list where i want make list of points "pointlist:=list, pointlist.new(2,5),etc.(few points)" and i want to get list of my points related to variable poinlist.... so i need: make a new type: "point" and object "list" which can handle data of point type... how canI do this?
