    Graduate Deriving the Witch of Agnesi Curve

    Hello, I have encountered an exercise in my differential geometry book: to derive the parametrisation and the cartesian equation of the curve witch of Agnesi. To see how it is constructed please see: http://en.wikipedia.org/wiki/Witch_of_Agnesi" How would one derive the results? I am...

    Only using properties of gcd, in two steps you get (n!+1,(n+1)!+1) = (n!+1,n), and by the Euclidean algorithm, n!+1 = n(n-1)! + 1, has remainder 1, hence coprime. kingwinner, good luck with MAT315.
