I'm using Maple 15 with Suse Linux 11.4

Export to latex produces a tex file which, when conveted by pdflatex contains all sorts of errors. The page margins are very large, parts are missing, the title appears alone on a page, lists of equations don't have line breaks so, for a long list you find just the central part going from edge to edge of the page.

I gave up using "Export to latex" on earlier versions. I had thought that Maple 15 might be better, but it seems worse.

Hi,

Q1) Could you pls tell me how can I show in maple the curve (x^2+y^2)^2=x^2-y^2 in the form of

x(t)=cos(t)/1+sin^2*t and y(t)=sint*cost/1+sin^2*t.

Q2) how can I express sin^2(4x) in terms of powers of cosx.

a) cos^3(3x)cos(5x) as a linear combination of cosines of multiples of x.

how can i solve matrix ?

for example :

I have a module to overload the * operator for the function f such that:

a*f(b,c,d) = f(a*b,a*c,a*d)

FPackage :=  module()option package;    export `*`;    `*` :=    overload    (      [        proc(a::algebraic, b::specfunc(anything, f))          option overload;          map2(:-`*`, a, b...

Hi 

Could uou pls tell me how to do a parametric representation of the curve in maple where curve is define as

(x^2+y^2)^2=x^2-y^2 . Secondly how to plot this curve.

ex:

for N=4

hey,i'm trying to divide the values i get using this 

y := 23.45*sin((360*(x+284))/365):

seq(evalf(y), x = 1..365); 

by some imported data....how do i do this?any good advice will be appreciated.Thank you in advance

How to find the sum
sum(tan((1/180)*(4*j-3)*Pi), j = 1 .. 45)

 explicitly? Of course, with Maple.

Hello,

I am trying to solve a system of six equations with the command solve. Unfortunately I only get the message "Warning, solution may have been lost". If i try to solve only five equations, i get an answer, that could be right.

My questins is: Is there a mistake in the syntax of solve? Or, is my equations system wrong?

Thank you!!!

Maple code:

> restart;
> FZ := 0 = FLZ+F11Z+F12Z+F21Z+F22Z+F31Z+F32Z;

I've this task to deliver to my teacher, yet when i try to open up my maple file, it appears to be corrupted (i've no idea why) i used it last night without any problems? ...

The only part that opens is the headline...

Need assistance!

Ive tried several commands, but none of them will give me a response

Here are the points im working with:

u = (2, -3, 1), v = (-4, 3, 3), w = (2, 4, 6)

And here are the several commands ive tried to use, with "with(LinearAlgebra), with(geom3d)" implemented before:

1. 

volume([2, -3, 1], [-4, 3, 3], [2, 4, 6], parallelepiped)

> with(plots, display);
> volume;

display(parallelepiped, axes = normal, scaling = constrained, orientation = ...

I have 91 points and to take the sum of the y-coordinates, I do

sum('points[k,2]','k'=1..91);

But if I want to take the sum of the points on just the even indeces i.e k=2, 4, 6, 8, 10...etc, I try to do

sum('points[2k,2]','2k'=1..91)     

but Maple gives me an error. I'm doing something wrong here. Help me please me fix the syntax error!!

Hi,

I am using Maple first time to solve equations. Equations and error message are as belows:

> solve({a(3.05-c)^b = 0.7400000000e-4, a(3.10-c)^b = 0.1806000000e-3, a(3.75-c)^b = 0.5840000000e-4}, [a, b, c]);
Warning, solutions may have been lost

Any solution, what is going wrong?

Have a piece of code:with(Optimization):

with(ExternalCalling):
MyTargetMultArgsFunctionExt := define_external('MyTargetMultArgsFunctionExt', 'MAPLE', x::(float[8]), y::(float[8]), 'LIB' = "maple_library.dll");
G := proc (x, y) options operator, arrow; MyTargetMultArgsFunctionExt(x, y) end proc;
dMyTargetMultArgsFunctionExtr0 := proc (x, y) options operator, arrow; x^2 end proc;
Minimize(G)

After which i obtain warning:

Hallo

I'm new in Mapleprimes and I'm looking forward to interesting discussions.

I was just wondering if and how it would be possible to use Maple for something like proving invariance of trace under unitary transformation.

So

tr(\Omega) = tr(U^{+} O U)

and

U^{+}U = I

After a number of reformulations, one arrives at an expression tr(O) = tr(U \Omega U^{+}).

Another example would be to show that (AB)^{-1} = B^{-1}A^{-1}....
