I have a list contains the triagles with in each triangle has mesure of the angle AOB equal to 45 degrees. Now I want to select four points in list so that they lie on the graph of the funtion y = (ax + b)/(cx + d), where c <> 0. This is the code which I make the list.

I want to use Maple (dsolve command) to solve this problem, how do I input the command? Part (a) is enought.

I have tried the command, but Maple says "Warning, for {u(t)} arbitrary the system is inconsistent".

Thank you very much for your help.

hi maplefriends, i´m trying to solve a piecewise funtion, and gold is find the maximum and  location, for that i use de package Maximize.unfortunately the result i have is the local maximum, can anyone show me, how can i do that? >  >  Download maximize_abs.mwbest regards

I might be doing something wrong here. But when I ask Maple 17 for the integrating factor of this ODE, it does not match the result if I find the integrating factor directly.

restart;
with(DEtools):
ode:=2*t*y(t)+t^2*(diff(y(t), t))+t^2*y(t)-2*y(t)-t*(diff(y(t), t)) = 0;
intfactor(ode);
simplify(exp(int( (t^2+2*t-2)/(t^2-t),t)));

Why I am not getting the same result from the last 2 commands above?

 

Can someone tell me how to solve the copy&paste problem? Every time i want to copy&paste an integral i get this error "Parts of the expression are ambiguous please select one of the suggested meanings".

Its really frustrating! 

Hi my friends                                                                             ...

A contest is being held.  The three prizes are a $2000 vacation, 1 paid week off work and a $500 camera pack.

In order to enter 1 ticket in the draw you have to contribute $1 per paycheque for the year.  So since there's 26 pay periods in a year each ticket will cost you $26. You can contribute as much as you want.

Let's say there's about 1600 employees in the company. 

How many tickets should you buy to maximize your chances?

Hi,

I am trying to solve system of equations as

and , with c as parameter and f and g are nonlinear function in y and c. My friend suggestedme to use continuation method for this in Matlab. So is there any way...

Good afternoon sir,

 

Some of the Problems related to Numerical Analysis consuming much of time when solved using Maple.

I noticed at the bottom of Maple worksheet Evaluationg in animated form for a very long time.

How to overcome this type of problem in Maple. Please kindly suggest the best method.

 

with regards

Good afternoon sir,

 

I am getting frequently error message while finding the approximate value using False Position method

for the function f=1+x-2sin(pix) 0<=x<=0.5

If I replace pi by 3.14 it is giving the result. Please solve this problem for me.

 

with regards

Hello,

I have a question about 'combining' procedures, in like: I would like to write a procedure which refers to a formula containing already a procedure.
I know somebody already posted a sort of similar post in 2009, http://www.mapleprimes.com/questions/36874-Calling-Procedure-Inside-Another-Procedure, but I'm missing the point of what's happening over there...sorry for that.

I just would like to know a general form of how to use a procedure 'inside' another procedure.

Well, in my case I have a formula (let's say 'equation1') containing a procedure which eventually draws a line. Later in my worksheet I use a formula ('equation 2') which is a procedure too, in which I want to substitute a parameter into 'equation1'. But because 'equation1' already contains a procedure I don't know how to solve this situation.

It's pretty hard to explain it on paper, but I hope it's clear.

I am supposed to implement the following code in Maple (I am using Maple 16 for Mac):

 euclid:= proc(m,n) local q,r1,r2,r3;

r1:=m; r2:=n;

while r2 <> 0 do;

q:=iquo(r1,r2); r3:=irem(r1,r2);

lprint(r1, '=', q, '*', r2, '+', r3);

r1:=r2; r2:=r3; od;

RETURN(r1); end;

 

It just returns: "Error, unable to match delimiters". I copied (typed) the code from this PDF:

I have to calculate and plot the volume of a cicloid where a equals 27. Now, the assisstant gave us the supposed code to work with, as most were having trouble with it. Here it is:

 

with(plots)

plot3d(27*(t-sin(t)),sqrt((27*(1-cos(t)))^2)*cos(s),sqrt((27*(1-cos(t)))^2)*sin(s),t=0..2*Pi,s=0..2*Pi);

 

However, this gives me the following error when trying to execute:

 

Error, (in plot3d) bad range arguments: ((27-27*cos(t...
