I have the following problem:
(K denotes kappa, Y denotes gamma)
Calculate the curvature K(t)= (||Y'(t) X Y''(t)|| / (||Y'(t)||^3))
of the parametrized curve
Its derivatives are;
I only need the cross-product OR the determinant of the matrix
and I cant remember from LinAlg how to do it...
Hope one of you wizes out there can help me =)
