[sage-support] Re: Step by step result
I am trying to do the same as Mathway, however, with a real step-by- step result instead of redirected to a commercial software. I want to help high school and first year college students to learn math and I want it to be based on Open Source technologies. As long as there is some ways to do it with Sage, I don't mind investing the time and learn it.

Derive itself was killed as a product, so AFAIK you cannot buy it any more. The same is for exmaple in maple for derivatives and integrals, you can try it online athttp://cgi.math.muni.cz/~xsrot/int/uvod.cgi?cnt=yes The checkbox Zobrazit postup výpočtu: means show steps. In Sage you can write some worksheets which solve selected typical problems, just like Maxima andhttp://user.mendelu.cz/marik/maw/od Mathematica andhttp://calc101.com/ The following post could be also interestin for you:http://thread.gmane.org/gmane.comp.mathematics.maxima.general/23736/f...

Thank you for this info, I will download and play around with it. Too bad it's not open source.

This is for a completely different audience than Sage, and is only free, not open source, but may be useful to you. I believe it is only one of many such things, but it is the first one that came to mind.

[sage-support] Re: Step by step result
Hi, great idea, but remember that computer algebra systems use slightly different way than humans to solve problems... I think than more people work on something like this -- just guessing from questions like http://thread.gmane.org/gmane.comp.mathematics.maxima.general/23048/focus=23051 and http://thread.gmane.org/gmane.comp.mathematics.maxima.general/9291/focus=9292 I am maintainer of MAW, Mathematical Assistant on Web, which *is* opensource, see the page at http://user.mendelu.cz/marik/maw/index.php?lang=enform=main sources at http://mathassistant.cvs.sourceforge.net/mathassistant/ and perhaps the VMware virtual machine at http://user.mendelu.cz/marik/maw/offline.html MAW can solve selected typical problems like evaluation of integral, double integral, derivatives etc in steps. The main idea is that the user input is processed in a worksheet. So the worksheet for solving quadratic equations could look as folows 1. Get a,b,c 2. Print a*x^2+b*x+c=0 3. If b=0 convert into a*x^=-c, take square roots and finish 4. If c=0 convert into x*(a*x+b)=0, return answers and finish 5. Find b^2-4*a*c 6. Evaluate sqrt(b^2-4*a*c) 7. Find answers x_1,2=... However, computers can never emulate the human approach. As an example consider the problem to differentiate the function sqrt(x)*(x+1). Both MAW and calc101.com use product rule to find derivative, but much simpler is to multiply the parenteheses first and continue with sum rule. The first way is computer way the second one is human way. Similarly when differentiating something like (x^2+x+2)/(x^3) --- quotient rule is far more complicated than algebraic modification and sum rule for derivatives.

[sage-support] GCC for Mac OS X
I wrote couple sage scripts and would like to compile them in Mac OS 10.5. Looks like I need GCC. How can I install one? A quick search on the internet seems to suggest that I need to sign up as an Apple Developer to get a copy which I don't feel comfortable to.

However, to keep up to date with the newer builds of the tools, you need to sign up for a free account on their developer site.

[sage-support] Re: GCC for Mac OS X
Thank you all for the quick replies. Yes, those are sage scripts but I preparse them into .spyx files and hope them run a little faster after compiling. Alright, I will give ADC a try.
