As pointed out by Mike Honeychurch in the above comments, the first place to start would be to look at the documentation on differentiation. pdf).I've personally found the "help" mechanism in Sage quite valuable.Your solution was almost correct, except that it should make f an argument of the hessian function and could implement the derivatives in a more compact way.
See also Sage Documentation, where you can find tutorials, manuals, references, etc. More details available here Wikipedia on Sage. Graphics: Matplotlib, Tachyon3d, GD, Jmol Graphical Interface: Sage Notebook, jsmath Numerical computation: GSL, SciPy, NumPy, ATLAS It has an online version: Share Cite Follow edited at 5:50 answered at 1:30 Rory O'Kane 253 2 10 Add a comment 10 Checkout which is a SymPy session that runs on the Google App engine. compounding weekly for 5 years the values can be changed and the function re-executed. Mathics is a free, light-weight alternative to Mathematica built using Python and SymPy. To solve a problem with a principal of 300 at 3 p.a. Linear Algebra: ATLAS, BLAS, LAPACK, NumPy, LinBox, IML, GSL So far Mathematica is basically operating as a calculator. (You can also peruse sample "Worksheets" from "notebooks").Īnother "plus" about Sage Notebook is that you can create folders, save your work, etc, on-line, and can then thus access it (when on-line again) and pick up where you left off at another time.Īrbitrary Precision Arithmetic: MPIR, MPFR, MPFI, NTL, mpmathĪrithmetic Geometry: PARI/GP, NTL, mwrank, ecm You can create your own account if you scroll down to the bottom of the webpage linked immediately above. I'm not sure about its graphing capabilities though it does seem to come equipped with some graphing functionality. (see more programs listed below), and you can program, as well (Python?). I can't speak for hicalc (I've not heard of it!) but IMO, a good choice would be Sage Notebook: it integrates a whole bunch programs: GAP, R (statistics), Pari, etc. That may help you ultimately determine what works best for YOU! Various systems are listed in tables, each identifying cost, features, etc. Added: I found the Wikipedia article Comparison of Computer Algebra Systems from a link on Sage's site.
