Hello, here is my problem Define a triangle with the 3D vertices in this (positive) order: Vec{X1}=(x1,y1,z1), Vec{X2}=(x2,y2,z2), and Vec{X3} =(x3,y3,z3). Write down the vector components of the cross-product (explicitly in terms of x1, y1, etc.): Cross[X2 - X1, X3 - X1] = ? How is this related to Cross[X1 - X3, X2 - X3]? Can anyone help? Thanks!
