[sage-support] Re: solve doesn't always solve
Hi Stan,
I don't think there is any other way to solve an equation such as that
in Sage. You can do it using Sage's interface to Maple (if you have
it installed / access to it), but it's not as clean as it should be
due to bug #3610.
sage:
var('wcnew,epsln,ysnew,delyu,sumsunew,sunlayersnew,delyu,nlayers,ysnew,cz,zr');
sage: eq = wcnew==epsln*(ysnew + ((delyu*sumsunew +
sunlayersnew*(delyu*(1 - nlayers) + sqrt((cz - ysnew)*(cz -
zr*sqrt((cz - ysnew)*(cz - zr)))/(cz - zr))
sage: meq = maple(%s = %s%(repr(eq.lhs()), repr(eq.rhs(
sage: ans = maple.solve(meq, ysnew)
sage: ans = sage_eval(str(ans).replace(\n,),globals())

Hi Adam, Sorry for the delayed reply.

You won't be able to do this until we have a native port of Sage to windows. We are working on one; it is one of the top priorities for this year. The Sage distribution is a total of 5 million lines of code, so this is a fairly nontrivial undertaking. In the meantime you could copy your module test.py into the vmware virtual machine and import it there (i.e., it would be in the virtual machine's linux filesystem). -- William --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
