    Good Morning Sir,

    My comment is on Vector Cross Product.

    Our note (power point slides) show gi.gjxgk = Eijl = √(g)εijk

    My understanding is gjxgk=εijk gk=√(g)εijk ( as the cross product of two vectors which produces a vector perpendicular to both i and j and the Levi Civita Symbol serves as the direction)

    Would appreciate this clarification.

    Thanks, best regards

    Taiwo Atinsola drew my attention to an error in question 53. The circle cross on the RHS should simply be a cross product. Please let all take note.
