In this video I continue with my tutorials which cover the necessary vector calculus for classical electromagnetism which is pitched at university undergraduate level. Specifically in this video I discuss how we calculate the vector which is perpendicular to or 'normal' to a function. This is important for Lagrange Multipliers and our studies of electromagnetism.
