[sage-devel] Re: Issue with quick start

In French, we name that "les mathématiques"... ISTR that there are serious etymological reasons. The US's "math" sounds like carelessness (and the french "désinvolture" would be a better designation...). -- Emmanuel Charpentier Le mercredi 29 novembre 2017 01:03:05 UTC+1, Matthew Schroeder a

[sage-devel] Issue with quick start

In the headings of the quick start it says things like "Symbolic *Maths*" and "Numerical *Maths*" It is MATH not MATHS. -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To unsubscribe from this group and stop receiving emails from it, send an

[sage-devel] Re: solve and conjugate bug

Hmmm... sage: assumptions() [] sage: (z-4*conjugate(z)).simplify() -3*z sage: assume(z,"complex") sage: (z-4*conjugate(z)).simplify() z - 4*conjugate(z) Explicitly telling "var(z,"complex") has the same effect... This seems directly inherited from Maxima : (%i29) ratsimp(z-4*conjugate(z));

[sage-devel] io_shapes_las missing in saga_cmd in fresh linux install

Hello everyone, First all, I am completely new to SAGA as well as GIS. However, I thinks this perhaps just a configuration error on my side on my linux host. I am using arch linux with gcc 7.2.0 I have just cloned the recent version from git. [michael@moo:saga-gis-code|master]$ git remote

[sage-devel] Re: solve and conjugate bug

This is probably related to the following: sage: var('z') z sage: (z - 4*z.conjugate()).simplify() -3*z which is a bug, given that the documentation of var says: By default, var returns a complex variable Eric. -- You received this message because you are subscribed to the Google Groups

[sage-devel] solve and conjugate bug

Is the following a known bug? sage: var('z') z sage: z0all = solve(z - 4*z.conjugate() == 1 + 3*I, z); z0all [z == (-I - 1/3)] sage: z0 = z0all[0].rhs(); z0 -I - 1/3 sage: (z0 - 4*z0.conjugate()) - (1 + 3*I) -8*I Clearly, the result of solve is not a solution of the given equation. -- You
