MaplePrimes Questions

I need to create an iterative code to find the minimum of the function


where x and b are vectors in R^2 and A is a 2X2 symmetric positive definite matrix. The implications of this is that the gradient of the function is


and that we are indeed searching for a minimum.

This is the code I have so far, using the while command to create a loop.

(a)Assuming the probability of obtaining heads in a coin toss is 0.5, compare the probability of obtaining heads in 5 out of 10 tosses with the probability of obtaining heads in 50 out of 100 tosses.

(b) For a set of 10 tosses and for a set of 100 tosses, calculate the probaility that the fraction of heads will be between 0.445 and 0.555.


I want to compute a define integral as follows:


I'm working on a computational physics project and prefer to use Fortran codes (compiled by MVS-9) with Maple power together.

In recent days I've changed some compiler options in MVS and unfortunatly (I don't remember the options) nothing works well as before.

For example, as I try to use a simple code like this:

Dear Mathlovers, The probleme is that i have created an animation for the mandelbrot set. The only probleme is that the axes dont rescale. Can anyone solve this. The animation is a zoom in on a point with 5 frames. Code is bottem of the post Grtz Pieter Excuse me for my bad english Code : ------ mandelbrot:=proc(x,y) local c,z,m; c:=evalf(x+y*I); z:=c; for m from 1 to 75 while abs(z)
Hello! Is it possible to transform the following expression, the way that instead of sin(x) I'd like to have cos(x) functions. Which command does this? k1*sin(x) - k2*sin(2*x) Thx!

As far as I know -- knowledge gleaned from various past mapleprimes posts I was able to read on the matter -- the recommended way to produce animated gifs is (1) to produce the animation within maple, (2) to save the relevant part of the worksheet as html, and (3) to retrieve the gif that the conversion produces (located in a folder typically named 'images' and that is attached to the html file created by conversion). It is then recommended to use other software to modify the gif -- my interest here was in selecting the number of frames per second.

I have a polynomial in powers of R where a_n are coefficients


I am trying to write R in powers of A.

So if n=3 we have



Is it possible to take the values from a matrix in maple into a spreadsheet in microsoft excel?

if so how do i do this?


I want to make a 3D plot with a logarithmic scale (specifically I want the Z-axis to be logarithmic, but I'm sure later I will want the ability to make any axis logarithmic).  How can I do this with Maple?  I've searched the net extensively but could only find one example of this, which was a maple application someone wrote over 7 years ago.  Needless to say this mpl file does not work with Maple.

pls solve this

Question says: Start with the square [0,1] x [0,1] and remove the middle square [1/3,2/3] x [1/3,2/3]. Divide the part of the original square that remains into 8 congruent squares each have side of length 1/3:

[0,1/3] x [0,1/3];   [0,1/3] x [1/3,2/3];   [0,1/3] x [2/3,1];    [1/3,2/3] x [2/3,1];   [2/3,1] x [2/3,1];    [2/3,1] x [1/3,2/3];   [2/3,1] x [0,1/3];  [1/3,2/3] x [0,1/3]

Could anyone help me on how to find a median of a triangle on maple? the questions is asking for a triangle ABC , write a maple procedure which has vertices A,B, C as input and which has a out of the point P (centroid) and a plot of the triangle with the three medians.

Use Maple to calculate the volume inside both the sphere x^2 + y^2 + z^2 = 4 and the cylinder (x-2)^2 + y^2 = 1.  Plot both surfaces on the same graph.

I need help! I have no idea how to do this on Maple!!
