[sage-support] Moodle, Stack question, Twisted server, math grant money
Is anyone interested in collaborating for some of the math education grant money? I have already create the following online math learning system. Check out the demo movies. Eduscape’s online math learning system Features • Thousands of pages of content(html) • Quizzes – Using the Stack Question(Maxima CAS – based) 1. Many forms of the correct answer 2. Gives partial credit(rubrics) 3. Worked solutions 4. Random questions 5. Multiple part questions on the same page(step by step progress) • Math learning movies (Camtasia) • Moodle (learning management system) • Twisted math server (allows students to get interactive math help). The following servers are ready – Algebra, Calculus, Differential Equations, and Statistics.

We would like to get involved in acquiring grants with educational institutions.

[sage-support] maxima-great stats
I am using the stats package in Maxima. Works great. Don't have to
use "eval". I developing a function for the student tTest. take a
list for the data. I put some bad data in the list --example-
[44,55,55/0,14*2]. Maxima takes the list in and finds the divide by
0. By the way the "14*2" works also. If I put the try-exception on
the input from the html page. The server hings up. Where do I put
it?
My function is below
def tTest(self,data1,conf,alt,mean_):#this works
maxima.load("stats")
dat =data1;con="conflevel="+str(conf);alt1a="alternative="+str
(alt)
me_="mean="+str(mean_)
a1=maxima.test_mean(dat,con,alt1a,me_)
a2=str(a1)
str1="Student tTest"
return str1,a2

[sage-support] maxima to sage
Is there anyway to convert a maxima expression
('sage.interfaces.maxima.MaximaElement') to
('sage.calculus.SymbolicArithmetic')?
I need to use Sage's factor instead of Maxima's.

[sage-support] Re: maxima's '
Simon,
The reason I don't like \over is because I am using Asciimath for the
pretty print output on my servers. I couldn't get sMath to work.
When I use SR on an integral it calculates the integral. I do have a
Python book and have read it. It is too bad Sage doesn't have a hold
function.
It doesn't look like what I want is doable.
Thanks for your help (William and Simon).

Does anyone have a Sage hold frunction? Look at the code below

eq2=maxima.ratsimp(n1+n2+n3+n4)
return eq1,eq2
Input
a1=LikeSimplify1a('-2*(-x-2*x^2-x)','-sqrt(12)-x','-2*(4-10)','10');a1
[0];a1[1];#a1[2]

Output
---
'-2*(-x-2*x^2-x)+(-sqrt(12)-x)+(-2*(4-10))+(10)'
4*x^2+3*x-2*sqrt(3)+22
This is in the notebook and is about what I want. When I use it on my
server the -sqrt(12) becomes -2sqrt(3). I don't want this. Can
anyone help me with a hold function that works in a Python script?

[sage-support] 1-dim display(notebook)
Is there anyway to have output in the notebook be 1-dim like input? expand((x-2)^2) would produce x^2-4*x+4, not the 2-dim output or pretty print. It seems like I have done it before. Maybe SR(). I would like to copy the output and use as input.

[sage-support] Re: latex
Yes, your right. I am latexing a value from maxima.solve(x^2-x-3,x).
Then maxima.rhs(). Then latexing the value. It still gives me the
\over. I am using 3.4.
When I assign it to a variable it works as below. If you would try
a1=maxima.solve(x^2-x-3,x)
R1=a1[0]
R3=maxima.rhs[R1]
latex(R3)
produces -- {{1-\sqrt{13}}\over{2}}
not good

[sage-support] latex
If I have this a1=-(sqrt(13)-1)/2 in a variable, then latex(a1) it
produces -{{\sqrt[13]-1\over[2}}.
If I do latex(-{{\sqrt[13]-1\over[2}}) get \frac{1-\sqrt{13}}{2},
which is what I want.
This is in a function. I need the latter. The \over does not do the
pretty print.
Is there a work around?

[sage-support] Re: twisted server
Alex, you lost me.
Here is the start of my code for the render
-
#This new html page for the calculation
class rwrite(Resource):
def render(self,request):
request.setResponseCode(402)
request.write("""
Equation solver
---
I have a request.finish() at the end.
It works OK in IE8.
I get a "request.finish" done twice warning. I load it in FireFox
and it kind of works. At times it displays html code and I refresh
the screen and the apage shows.

[sage-support] Re: twisted server
Alex,
Works great. But I need a link from the first page to load another
page. Here is my code
--
from twisted.web.server import Site
from twisted.web.resource import Resource
from twisted.internet import reactor
from twisted.web.static import File
class PaymentRequired(Resource):
def render_GET(self, request):
request.setResponseCode(402)
return "Please swipe your credit card."
class menu(Resource):
def render_GET(self, request):
request.setResponseCode(402)
return "http://192.168.1.101:/buy/
>Integrater"
root = Resource()
root.putChild("foo", File("/tmp"))
root.putChild("bar", File("/lost+found"))
root.putChild("baz", File("/opt"))
root.putChild("varr", File("/var"))
root.putChild("buy", PaymentRequired())
root.putChild("men", menu())
factory = Site(root)
reactor.listenTCP(, factory)
reactor.run()
--
It will not load the second page.

[sage-support] Re: jsMath working on server
Changed to AsciiMath. Working great. I have pretty print all over the server. Most of the functions have pretty print. Works great with FireFox even from a Linux box. If you use IE8 or 7 you will need to install MathPlayer. Try the text2speech function. Really nice. Right click on the math expression. The major problem was to get pretty in output. If anyone would like this setup on their server let me know. I have it working with a basic web service. Thanks for all the help with Sage and Python(Robert and Willian). I am using a Twisted server.

Cof1=maxima.args(eq10);Cof1a=Cof1[2];
val2=((1/2)*(maxima.coeff(eq10,x,1)))
Addon=maxima.ev(val2^2)
eq5=maxima.ev(val2^2)+M1[0]+M1[1]#this gets value from Maxima
eq6=factor(eq5);
eq7=-M1[2]+Addon;
Str1="This is added to both sides of the quad-- "
Soln=maxima.solve(eq1)
return eq3,eq2,eq10,eq6,Str1,eq7,Soln
---
The line that solve the problem was
Addon=maxima.ev(val2^2)
I now get a real number, that finishes the CS.
Willian, I need Maxima to write this function.
Here is some output.
-
the call ---val1=CSquare(2,-1,-2);val1[0];val1[1];val1[2];val1[3];val1
[4],val1[5];val1[6]
2*x^2 - x - 2 == 0
2*(x^2 - x/2 - 1)
x^2 - x/2 - 1
(4*x-1)^2/16
('This is added to both sides of the quad-- ', 17/16)
[x=-(sqrt(17)-1)/4,x=(sqrt(17)+1)/4]
-
the call--val1=CSquare(2,-1,-3);val1[0];val1[1];val1[2];val1[3];val1
[4],val1[5];val1[6]
2*x^2 - x - 3 == 0
2*(x - 3/2)*(x + 1)
x^2 - x/2 - 3/2
(4*x-1)^2/16
('This is added to both sides of the quad-- ', 25/16)
[x=3/2,x=-1]

Now to get it work on my server. When I finish I will give the link.

[sage-support] Re: Maxima Solve sys
JSmath is basically a bunch of javacript routines that takes latex
created from sage and displays in the html file. The html is
generated in my Python script(server,html). When I call JSmath the
first routine is loaded. In the first script it calls another and
this is where the problem occurs. One of the problems is that I am
calling the JSmath from a server. It is a path problem. I can insert
images in the html file.

No. The call is CSquare(2,3,4). Just trying to setup a random quad. Could this function be done with just Sage?

[sage-support] Re: Completing the square
Here is my start using Sage and Maxima. def CSquare(co1,co2,co3): eq1=co1*x^2+co2*x+co3 eq3=eq1==0 eq2=factor(eq1) eq4=(1/co1)*eq2 Cof1=maxima.args(eq4);Cof1a=Cof1[2]; val2=real(((1/2)*(maxima.coeff(eq4,x,1 val1=val2^2 eq5=eq4+val1 return eq3,eq2,eq4,eq5,val1 -- The val1 does produce 9/16. This is good, but when I add it to the lhs I get (here is my output) - 2*x^2 + 3*x + 4 == 0 2*(x^2 + 3*x/2 + 2) x^2 + 3*x/2 + 2 x^2 + 3*x/2 + sage261 + 2 9/16 Why the "sage261"?

I took out the eval and for some reason it is working.
Robert, this is function in my API (AlgCalc)
http://pirsqrt.com:1843/
If I would give it to you would you show me how to get JSmath to
work? I have talked to you before. You said you were too busy. I
have loaded load.js, but when it goes for another .js file it cannot
find.

[sage-support] Re: Maxima Solve sys
When I run the server with the function above and the following string
from a text box I get
[y=-1,x=0]. The string is "[3*x-y-1,x+(1/3)*y]"
It is changing the input value to [3*x-y-1,x]

[sage-support] Re: Load Maxima
Yes, that works.
However, I am trying to create a function that has Maxima functions in
it and I can't seem to pass values to it. I am using a Python
function.
Something like this
---
def Subs(x,y):
y1=maxima("float(x);");y1
maxima("p1:y1;");print maxima("p1;")
a1=maxima("s3:x*y;");
return a1
-
Is it possible to pass the variables into Maxima function?
