## Problem with solution due to RootOf...

y =

I cannot solve this for i. When I use maple I get a big result with a RootOf function that I don't know how to handle. I've looked around and I cannot find anything that will help me.

Can someone please show me how to solve this?

Thanks!

## How to change axis numeric formatting to scientifi...

Dear MaplePrimers,

The y-axis of my graphs consists of small values (<10^(-4)). Unfortunately, Maple displays a lot of numbers after the comma and it's not cool. Is there a command or option that allows to control the numeric formatting (scientific, engineering...) of a particular axis? Specifically, I need to change the decimal formatting to scientific notation. The x-axis is OK and not must be changed.

Regards,

Tuti.

## Exporting a maplet programme...

Is there a way of exporting a maplet programme into a universal programme so anyone can access it (someone who does not run maple)?

## Baby Names - The Visual Application Worksheet

by: Maple 13

A long while ago, I wrote a couple posts (part1 and part2) about mining data from the US SSA website.  I subsequently adapted the code from those blog posts into a visual application with sliders and interactive plots.  If you have played with the new ?MapleCloud functionality in Maple 14, you may have seen it posted already.

## Jet bundle with anticommuting variables (kind of.....

My question is this:

In with(DifferentialGeometry): with(JetCalculus) with(Physics):

I work with the following Jet Bundle:

DGsetup([x], [u, psi], E, 40),

where psi is declared anticommuting with Setup(anticommutativeprefix={psi}).

When I work with expressions that are differential polynomials in u with coefficients arbitrary functions of u, the EulerLagrange operator behaves correctly. The same is true if I multiply these expressions by psi or by psi_1 ...

## on infinite repeated function composition...

Let

G:=s->q(1-ps)^(-1)

be a generating function with 1-p=q in (0,1). Then the repeated function composition

G(G(G(s)));(G@@3)(s);simplify(%);

gives me some concrete expression. What is the simplest way to get the general expression for 3 replaced by n?

## Fourier series and partial sums of numerical value...

How to change this general form to solve :

How to calculate with Maple Fourier coefficients on some numerical valued functions and how to calculate and plot the 3 partial sums :

Function B : on the interval [-phi, phi]

f(x)= NUMERICAL (x – phi/2) + NUMERICAL (x+phi/2)

Function C : on the interval [-phi, phi]

f(x) =  NUMERICAL (x+phi/2)

## Heat equation in 1 dimention - help needed...

I enclose Maple general solution to the PDF heat equation in 1 dimention.

I need corrections of it to enable me to calculate the heat equation in certain conditions :

du(x,t)/dt - d^2/x,t)/dx^2 = ;   t>0, x belongs to interval [0,phi[

with boundary conditions :

u(x,0) = sin(x)cos^2(x) ; x belongs to interval [0, phi)

u(0,t) = 0

u(phi,t) = 0  ;  t is still t>0

## Fsolve and initial parameter values...

Hi,

I'm solving a non-linear system of equations (8 equations, 7 parameters) numerically using Fsolve.

Here's my problem: I run fsolve in a loop for different values of one specific parameter. What I would like to do however is have a matrix of parameter values and tell fsolve to pick a new row of that matrix each time as parameter values until it has run down all the rows.

I just need some general guidelines and the commands. Much appreciate the help...

## Highlighting issue not fixed in 13.02

If you highlight words that are above or below one another on an adjacent line, the highlighting does not highlight properly.
