Hello,

I have small script that uses syntax checker mint and latex command and latex to convert an expression in maple syntax to an image. But functional operators are causing me troubles.

Suppose I want to enter the equation  (x+1)*(x-1) and I forgot to use the star (*) for multiplication. The result (x+1)(x-1) is also correct because Maple thinks that I am using functional operator x. But I would like to evaluate this cas as wrong syntax. So I have to detect functional operators (somehow) but I don't want to detect operators such as +, -, * and so on.

Hi

I have this problem regarding how many employees (the variable x) is needed to get the lowest wage cost in a company. I have written the following model:

>restart:

>assume(x,integer)

>assume(x>=0)

>a:=16362-(40+x)*504:

>b:=IF(a<0,16362-(40+x)*420,(40+x)*84:

>c:=IF(b<0,16362,(40+x)*420)

>d:=IF(a>0,a*12.65*2.0)+IF(b>0,b*12.65*1.5)+c*12.65

hi,

tried to solve a least square problem with maple.

i've n=3 measured data

xi = 1, 4, 6

yi = 2, 4, 8

and have to create a optimised function of the type y=f(x) = px + q

i gave maple this input:

y := <2,4,8>;

x := <1,4,6>;

with(Student[LinearAlgebra]):

LeastSquares(x,y);

Can maple rsolve equations of the type y(t)=sum(b(t),1..y(t-1)) for y? Thanks.

Hi,

I'm trying to optimize parameters in a implicit function. I can create a plot of the function using implicitplot. But I now need to find the maximum and minimum in a given range. How to do this. 

I have been searching for quite sometime, but I cannot find an answer to this.  So at last, I'm posting.

I keep trying to solve this equation below, and this is the outcome I get.  And, I have no idea what the solution means.  I am largely confused by the percentage signs, periods, etc...

 

Thanks in advance!

Hi,

I have to filter a load of analysis data and have written the following

We have an area defined in polar coordinates by

r = 1..3 and theta = 0..3*Pi /4

, and we wish to plot it in maple. Such a simple thing should be possible, but it seems impossible with implicitplot and polarplot.

Unfortunately, this exact maple plot is required for an assignment tuesday, so we would like some help

Sorry because I can not good speak English. I want to draw a graph with maple 10.

I want to draw a polar contour. I have some datas in a txt file. I want to read data and plot graphic. My datas have 3 colums. first column is radius (r) ,second column is angle (theta) ,third column is my fuction z. z=f(r,theta).

I do readdata and my datas reading. But I not drawing a contour graphics.

How do I to solve this problem?

It's probably a simple issue but I can't figure it out

If I do 3/(4.)  I get .7500000000 .  Why doesn't maple drop the zeros? 

Is there a default so that when I divide a fraction like 3/8 or 1/4 and get .375 and .25 without the extra zeros?  or is it always standard for maple to tack on those extra zeros?

1. The toolbox "Maps" within the Maplesheet "Introduction to the mathematics of maps" is not loading.

2. The code maple.lib is stored in a directory c:/maps

3. The toolbox maps is refered to as:  libname:= libname,  "c:/maptools", "c:/maps";

Maple returns:    libname := "C:\\Program Files\\Maple 10/lib", "c:/maptools", "c:/maps"

4. The maptools is opening fine, but not the maps toolbox.

Hi,

I opened an older worksheet (from version 9 I think) and opened it in version 10. In the new version it produces different results.

In version 9 the solution found with the solve function included sinh and cosh terms. The new version uses their exponential forms. The expressions are now much bigger, but are probably the same in effect. However I would like to get the Maple9 behavior for this solution.

I have tried the convert (function,trigh) but that didn't result in the clean function I got in earlier version.

Any ideas?

Hi!

I want to set up a question where students first should do some calculation (p-values actually). Next step would be to see if this value is an element of intervals given by me. It seems reasonable to attempt constructing a multiple choice question, but there could be alternatives. In the case of a MC, the alternatives could be like the following:

1. <0.005

2. 0.005-0.01

3. 0.01-0.02

4. 0.02-0.025

5. 0.025-0.05

6. 0.05-0.10

7. 0.10-0.15

8. >0.15

Hi there :) I often need to plot datapoints, and then fit a curve in then. So far i did this with the [i]ScatterPlot[/i] command, and moddeled the function to the data with the Fit or Nonlinearfit command. In most cases this worked really great, but i would need some extras: ;) As far as i have noticed the Fit is only based on the datappoints. The Fitfunction doesn't seem to take care of x- or y-errors, drawed in with the data. So: Is there a way to take care of the x- and y-errors in the Fitting process? If yes, how?
