This is a simple web CAS (computer algebra system).
This CAS does not need any server, you are running it locally with the javascript
engine of your browser (need a recent browser, e.g. Firefox 19 or Chrome)
the 1.5M compressed CAS code is downloaded once (giac.js.compress javascript
compiled from native Giac/Xcas by emscripten) then uncompressed.
The javascript code is at least 10 times and often 100 times slower than the native
code, it is therefore recommended to run large computations with
Xcas!
Examples of input:
factor(x^4-1); cfactor(x^2+1); normal((x+1)^4)
solve(x^2-3*x+2=0); csolve(x^2=2*i); solve([x+y=1,x-y=3],[x,y])
simplify(sin(3x)/sin(x)); gcd(x^4-1,x^3-1)
f(x):=sin(x^2):; f(sqrt(pi)); f'(2); f'(y)
int(1/(x^4-1)); int(1/(x^4+1)^4,x,0,+infinity)
limit(sin(x)/x,x=0); series(sin(x),x=0,5);
A:=[[1,2],[3,4]]; inv(A); det(A-x*idn(A)); A[0,0]; rref(A); eigenvalues(A); eigenvectors(A);
