Purpose of use
To verify some Matlab code
Comment/Request
The first try (.5,.5) is way different than the result from my code or from Wolfram Mathematica's web site calculator, which agree with each other.
from Keisan
The function definition is different.
keisan: Π(n,k)=integral(0,1){dt/(1-n*t^2)/sqrt((1-t^2)(1-k^2*t^2))}
Wolfram: Π(n,m)=integral(0,1){dt/sqrt((1-t^2)(1-m*t^2))}
Therefor if convert k=sqrt(m), the same answer.

Comment/Request
slow so ok for single calculations. looks like it uses a c++ library on the back end. would be faster if the script was on the page
