plane, coordinates, standard basis, basisGiven a point P in the plane you can see its coordinates (x1,x2) with respect to the standard basis (e1,e2), or compute its coordinates (z1,z2) with respect to a different basis (v1,v2). The signed area of the parallelogram determined by this basis, det(v1,v2), is a crucial quantityComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Matemática
