## Origin of the French Curve, or mathematical defini...

Asked by:

Everyone knows what a French curve is. Heck, some of us even have a set kicking around. But I have run into a brick wall in trying to find out how a french curve is actually made, or defined. Over several sessions, I can find nothing on the net that even hints at the answer.

French curves have been in use for ages, and they must have an origin. Either they are generated using some kind of function, or they were perhaps...

hi i am seeking help for a little problem The question is a part of my coursework but it doesnt make sense to me i dont know how to use maple to construct a model can you please help thanks. On board sailing ships or warships, a lookout stood watch in a crows nest high on the main mast. b) Construct a mathematical model to show how far a lookout can see. Clearly indicate any assumptions you make and define any parameters you use in your formula and in the construction of your model. c...

## What is Special About the number 275305224 ?...

Asked by:
`as you know the number of solutions for order 3 to 5 magic squares is as follow : (not counting rotations and reflections)`

order 3: 1 solution

order 4: 880 solutions

order 5: 275305224 solutions

higher order: unknown ...

in the first look at 880 , simply appeared it can constructed by

## integrals in Maple...

Asked by:

int(sqrt(1 + sec(x)^2), x)

int(sqrt(2 + tan(x)^2), x)

With Maple 13, which is the latest version on the computer on which I tested these integrals (that originated with a

senior scientist in Australia), the former yields a reasonably compact answer, but the latter yields an extensive

output containing Elliptic functions of various kinds.  The two integrands are trigonometric identities.  What is the

problem here?

## Arnold's problem...

Asked by:

Here is one of the problems from "Mathematical Trivium"  (Russian Mathematical Surveys, 1991, 46:1, 271-278) by V. Arnold. Those problems are aimed at the strong graduate and postgraduate students of the top universities.
I find it remarkable that a big part of the Arnold's problems can be solved with Maple.

## MRB constant N part 2

Maple

I will use this post for a list of conclusions drawn from MRB constant N and the many similar approximations that I have found.

Let x= MRB Constant.   Each approximation is followed by a maple input so you can verify these approximations.

## MapleTA hiding some answers...

Asked by:

I want one of a sequence of questions to not show it answer. The other questions need to show their answers, but this one

cannot. I could make a separate assignment for this question but that seems rather painful. I use latex => .qu so the

solutions that don't require touching the editor is a plus.

## Is there a way to do a substitution in 2-D Math fo...

Asked by:

I'm doing some algebra with transfer functions, which are often written in LaPlace Transform notation, e.g. f(s) = 1/s.  One often wants to find the "gain and phase" of such, which is easy to do using the following steps:

1) Substitute "i omega" (imaginary unit, omega = frequency in radians) for s.

2) Express the complex quantity in polar (rho, phi) notation -- rho = amplitude, phi = argument (Phase).

So here's my question -- if I am developing...

Asked by:

Ok hello everyone and thank you in advance.
I have 2-3 difficulties in a maple plotting.
I'm trying to plot two fairly easy surfaces in maple 3d
What I want is:
3 standard axis, x,y,z with y vertical and z coming out of the screen(obviously you can turn it and stuff.)

Two surfaces:
On with y = (1/x), z=free;
The second with y= 2*x(1/z);
