thanks, it's very kind of you you answered me so fast.

You omit to add a semi-column on this line : resize(Imy,217,0)
And you forget to add the number of terms in the naf command. (here I
set 10 terms).

So the script becomes :

x=-pi,pi,pi/108;
y=sin(x);
vnumR Imy;
resize(Imy,217,0);
ff=file_fullname("test-data.tx t");
write(ff,"%20.15E %12.8E\n",y,Imy);

a weird problem with trip.

I've started using TRIP just today, my operating system is linux:
ubuntu,
I created a simple .t file to test TRIP's abilities as follows:
x=-pi,pi,pi/108;
y=sin(x);
vnumR Imy;
resize(Imy,217,0)
ff=file_fullname("test-data.tx t");
write(ff,"%20.15E %12.8E\n",y,Imy);
naf(216,ff,naft1,pi/108,-pi,1, 2);

Re: do trip has maple's expand command?

2009-12-07T19:33:24Z

TRIP can't handle expression , such as " cos(sin(x))" when x is
symbolic. It can handle it when x is a numerical vector.
If x is symbolic, it can handle expression such as "cos(4*x)".

Mickael,

do trip has maple's expand command?

2009-12-07T18:47:37Z

I have a problem.
I need to convert
cos(2*sin(x)+3*cos(x))
to
8*cos(sin(x))^2*cos(cos(x))^3- 6*cos(sin(x))^2*cos(cos(x))-4* cos(cos(x))
^3+3*cos(cos(x))-8*sin(sin(x)) *
cos(sin(x))*sin(cos(x))*cos(co s(x))^2+2*sin(sin(x))*cos(sin( x))*sin(cos
(x))

this can be done in maple using
expand(%, trig)

Ce serait pour effectuer des dérivations "classiques", algèbre de Lie, développement perturbatif, ..., avec choix de l'ordre du traitement de la perturbation.

Bonjour,

Effectivement, dans cette version de TRIP, deriv n'est pas encore
disponible.
La documentation est sur ce point en avance... Je vais modifier la
documentation tant que cette fonction n'est pas disponible.

Quels sont vos besoins concernant la dérivation ?

Mickael,

Derivation

2009-11-27T14:00:55Z

Bonjour,

En testant TRIP, je me suis aperçu que la commande "deriv" pour la
dérivation ne fonctionne pas.
Avec l'exemple donné dans le pdf j'obtient:

s(t) = 1 + 1*t

TRIP[ 3 ] : Fonction 'deriv' inconnue
Commande :'s2=deriv(s,t)$'

TRIP[ 1 ] : Erreur de syntaxe
Commande :'? deriv;'
