For the paraboloid, the gradient was ∇f(x, y) = (2x, 2y). For the cone, the gradient was ∇g(x, y) = (x/√(x^2 + y^2), y/√(x^2 + y^2)).
The 6th edition of "Multivariable Calculus" by Edwards, Henry C., and David E. Penney is a well-written and comprehensive textbook that provides a solid foundation in multivariable calculus. The book's clear explanations, abundant examples, and emphasis on applications make it an excellent choice for undergraduate students. While some students may find the theoretical aspects challenging, the book's strengths outweigh its weaknesses, making it a popular and effective textbook in the field. For the paraboloid, the gradient was ∇f(x, y) = (2x, 2y)
