I'd like to have some tools for applied problems in optics and some other areas of engineering where lengthy analytical expressions arise and numbers get inserted to calculate observable quantities, uncertainties, and such. I'd ultimately use Sage/Sympy/Python in some combination to check hand calculations as well as do harder calculations.
Since Sage incorporates many Python-based packages I thought to ask whether it preserves options such as complex=True in expand(). Perhaps Sage's expand() is not the same as Sympy's expand()? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
