Hi! The following worksheet illustrates how you can use determinants in a variety of geometric applications. The worksheet outlines how you can determine the area of a triangle or a parallelogram, and the volume of a tetrahedron or parallelepiped using a determinant containing the coordinates of vertices. The worksheet also shows you how to obtain the equation of a plane through three points, and to determine if three points are collinear, or four poin

Recently i encouter a problem in Maple 12 that i had not with Maple 10...

More specific:

>g(x):=exp(1/x)+x^3;

>minimize(g(x),x=0.5..2);

with Maple 12 i get:

minimize(exp(1/x)+x^3,x = .5 .. 2)

while in Maple 10 i got the answer..

The g(x) has clearly a minimum in that range of x..

I was forced to take the first derivative and find the roots...

Please can anyone explain me why this happen??

 

i have problem to solve my program, please help me

thanks

How can I graph this in Maple and create an adjacency list.

I would really appreciate any reply back

I've recently updated to Maple 12 (on Mac OS X.4.11) and am still learning how to use it. A search on Maple FAQs didn't turn up any answers to the following questions.

So here's my problem: Find a continuous solution to the integral equation: f(x) = (1/2)*[integral_[0,1](x*y/(y+1))*f(y)dy + x^3] by finding a fixed point of the fucntion psi:(C([0,1]),d_inf) --> (C[0,1]),d_inf) psi(f(x)) = (1/2)*[integral_[0,1](x*y/(y+1))*f(y)dy + x^3] . Here, C([0,1]) is the set of all continuous functions over [0,1] and d_inf is the supremum metric. I honestly have no idea how to do this. My professor said this... A fixed point for the map psi is a solution of the integral equation.

 dear all:

   i have wirte a programme for a defined function as follows:

  med := proc (f1, f2, f3) if f3 <= f1 and f2 <= f1 then if f3 <= f2 then f2 else f3 end if elif f3 <= f2 and f1 <= f2 then if f3 <= f1 then f1 else f3 end if elif f1 <= f3 and f2 <= f3 then if f2 <= f1 then f1 else f2 end if end if end proc

#the med function is for get the mediume number from any givend three numbers.#

I am posting it again. I need the plot of W(i+1/2)=1/2*(W(i)+W(i+1))+1/2*sqrt(sagma*t)*g(i)    where g(i) is an independent N(0,1) sample. Please some one help. i have attached a file of the plot which I need.

How to write expression with customized physical units in maple 12.

For example I want to how write the volume units in microliters.

Hello,

I am trying this evalm example (from the help page of evalm, Maple 12):

restart;

alias(Id = `&*`());

# Simplification of matrix operations

evalm((`&*`(`&*`(A, B), 2))*B-`&*`(B, Id));

 

Error, (in evalm/amperstar) &* is reserved for matrix multiplication

A and B are not defined as Matrix in the help page. Is it the problem?

 

 

So given characteristic polynomial of a 2X2 Matrix of char (A,x) = (x-1) how do I find all possibilities for the Jordan and rational canonical forms?

Thank you!

Hi to all

I want to convert a maple file to Latex. How it sholud be done. Any one can help me.

Thanks

Hi Maple experts,

hi, I have 12 equations that I want to solve, when I try to solve them using maple 12 it gives me nothing just empty [ ]  but when I remove an equation from them, maple solved the other 11 equations !!

but i want to solve the 12 equations together.  the equations are :-

exp(-z[1][1]/t[1])*(sum(p[2][j]*exp(-z[2][j]/t[j]), j = 1 .. 3))*(sum(p[3][j]*exp(-z[3][j]/t[j]), j = 1 .. 3)) = t[1](1-w)/(p[1][1]*w),
