Excellent class and excellent lecturer, i think that the guys didnt see the basis of linear algebra thats the reason that prof Auroux gave them an introduction of analitic geometry and elemental algebra, there are assignments that in Mexico are elemental at Facultad de Ingenieria UNAM: algebra(real numbers,  complex numbers, polynomials, ecuation systems and matrices), analytic geometry (polar curves, curves at space, vectorial algebra, surfaces), linear algebra (vectorial spaces, transformations, change of bases, function dependence; linear combinarions and theorems) obviously differential and integral calculus and finally in elemental maths vectorial calculus(multivariable calculus) that is linked to this, but prof Auroux resumed the basis in 2 hours thats awesome####[['class', 'Course_General_Feedback', 'POS'], ['lecturer', 'Instructor', 'POS']]
