I am new to maple and I need help.

Let x=x(t) and y=y(t) be functions in t. Suppose that x'=2x−5y+t and y'=4x+9y+sint such that x(0)=y(0)=0. Find y(1).

How do I go about doing this question?

Thanks

Hi EveryOne!

In the the answer of the question "How to find roót of polynomial in finite field and extension finite field (at URL: http://www.mapleprimes.com/questions/203977-How-To-Find-Roots-Of-Polynomial-In-Finite#answer215097). Carl Love helped compute eigenvalues (x1,x2,...,xn)and eigenvectors of the given matrix M over GF(28)/(y^8+y^4+y^3+y+1).

I need to do:

1. Get matrix D from these eigenvalues (x1,x2,...,xn), with D[i,i] = xi and D[i,j≠i] = 0 (D will be diagonalizable matrix. Some xi may be in extension finite field  GF((28)2))

2. Get matrix P from eigenvectors corresponding to the above eigenvalues, compute P-1

3. Compute matrix B = P x D1/4 x P-1 in  extension finite field  GF((28)2).

Please help me!!! 

My task is to develop a mathematical model of time-variant temperature
distribution in a bar with Maple. 
The bar is made of aluminum. The length is 202 mm and the diameter
is 8mm.
Heat is supplied from the kitchen lighter where the flame burns on butane.
The height of the flame is about 4 mm.
Your model should be able to answer how long the time it takes to reach
a certain value of temperature at the distance of 10 cm from the heat source.

 

anyone can help to answer this? im totally new to maple.. hopefully some1 can help me to answer this..

Please see attached document.

 

The 2 bits of data I am working with are a Constraint Function and Objective Function:

 

 

I need some pointers on how to do this. I keep getting solutions of

and I am ont receving an x value for some reason and leaving me unable to continue with the problem.

If anyone can send me some code I would be grateful. If anyone would like to send the correct full working code so I can see how to do this and review it I would be grateful.

 

 Code I had so far was:

 

 


 

Write a Maple code that performs the Gaussian elimination for an nxn matrix, converting it to an upper triangular matrix. 

(Hint: you will need to use three for .. do loops.)

Write a recursive Maple procedure, called “decToBin”, that converts an integer from decimal (base 10) to binary (base 2). Ensure that only integers are allowed as arguments to the procedure. Passing a negative integer should result in no output. Test your procedure by outputting the result of the following:
decToBin(10)
decToBin(163)
decToBin(213)
decToBin(-1)
decToBin(“A”) # should result in an “invalid input” error

Hello,
I am looking here for a tutor, that can help me doing some Maple programming.
I am a mathematic student and we use Maple programming.
I will be happy to pay a small amount of money for each exercice you help me doing,
Obviously the money will not be much, as I am just a student, I am just thinking you help me , and the money I pay you will be just as a Thank you gift, I thought about asking tutors at the college, but they are charging too much :( 
if anyone is interested, please contact me here.

(The procedures that we usually have to write are for example:
Aitken’s method, Newton-Raphson Method, Chebyshev Polynomial,...  I don't think it is hard for you.
Thank you very time for your time and your help.

Hi Clever guys,
I am sorry if I asked for too much, but I am really in a big problem, I had a family problem and I didn't attend most of the lectures, and now I have to hand in an assignment before easter hollydays, and to be honest with you, I don't know from where to start, I know I will have to understand this stuff, but now I don't have enough time to do the assignment, so if anyone can help me, please please, for you guys it will maybe take 20min to do it, i ll need days and days and in the end it will be all wrong. I am going to try to do the other questions, there are 5 questions :(  
Please help me , I am really not a very bad student that just want to copie, but if nobody does this for me this time I will fell, please do this question for me please.. maybe you will say start it and then ask to check if it is correct, I am really trying my best, please.

that is one question:


By integrating a third order Newton Gregory Polynomial, derive Simpson’s

three eights rule given by

∫ f(x)dx (from x0 to x3 ) =3/8*ℎ(y0 + 3y1 + 3y2 + y3)

(b) Find the order of accuracy of Simpson’s rule and Simpson’s three eights rule.

(c) Write procedures to evaluate

∫ f(x)dx   (from x0 to xn) to a given number of decimal places using

i) Simpson’s rule.

ii) Simpson’s three eights rule.

The data to be input should be

i) The function f(x).

ii) x0 and xn .

iii) the number of decimal place accuracy required for the solution.

The output should comprise

 i) The number of strips used.

 ii) the value if the integral.





thank you very much 

Hello Everyone,

 

I would like  to write a code to calculate the riemann sum approximation of the curve sin(sqrt(x^2+y^2)+1 

calculate the actual volume using integration

use the ranges x=[-2pi to 2pi]=y, and 20 subdivisions.

also display the curve and the parallelepiped approximations on the same plot.

 my code give me  an error..please someone can advise me which part of my code is not correct..

Thanks very much in advance!

> g := proc (x, y) options operator, arrow; sin(sqrt(x^2+y^2))+1 end proc;

 Z := g(x, y);

 

 X := Array(0 .. n); Y := Array(0 .. n); Z := Array(0 .. n);

 

c := -2*Pi; d := 2*Pi;

a := -2*Pi; b := 2*Pi;

n := 15;

s := 0;

X[0] := a; Y[0] := c; Z := g[X[0], Y[0]]; s := 0;

dX := (b-a)/N;dY := (d-c)/N;

    for i from 0 to N do      for j from o to N do     s:=s+Z[i]*dX*dY     X[i]:=X[i-1]+dX: Y[i]:=Y[i-1]+dY: Z[i]:=g([Xi],[Yi])  end do;

This the error message i am getting (Error, unterminated loop)

hi everyone,

I need help writing a maple code to calculate the normal to the curve X^2-2X at x=1

and also display the curve, the tangent, and the normal on the same plot in the range x=[-2,2].

 

thank you for your help!

hello i need plot integrale of siampson thank you

Knowing that the Taylor series for cos(x) is:
sum := sum+(-1)^i*x^(2*i)/(2*i)!

How would I write the following Maple code?

Generate an animation sequence showing the Taylor series approximation of cos(x) from N=1..10, where N is the number of terms in the series. Each subsequent frame of the animation should show a more accurate representation of cos(x) than the previous one. Plot the animation from x = -2*Pi .. 2*Pi, y = -5 .. 5

How can I do if I wanted to simulate a class of 30 students rolling a dice 10 times, and you wished to count the number of 3's you observe for each student?
