Hi.
I'm writing the following code in order to plot sin(x^2+x^2) :
var('x,y')
g(x,y)=sin(x**2+y**2)
plot3d(g(x,y),(x,-5,5),(y,-5,5))
My problem is that the result is quite bad because of the sampling : all
the points with x^2+y^2=pi/2 are not taken, so that I don't get
beautiful circles.
How can I ask for a finer sampling, or to compute more intermediate points ?
I'm sure there is an option to add, but I don't see in the documentation
which one. (I'm reading the Sage reference manual, version 4.1.1, Agust
14 2009).
Thanks for any help
have a good noon
Laurent
