Question 1

Let M be the smooth 2-manifold R³, x = p(θ, φ) = (cos(θ)sin(φ), sin(θ)sin(φ), cos(φ), 0 ≤ θ ≤ 2π, and let

be a parametrization for M. If M is oriented by the differential 2-form ω = zdx∧dy, determine whether the parametrization p is orientation preserving or orientation reversing for M.

Question 2

Consider the unit cube Q =

in R³ with the standard orientation given by

.Express the orientations of the bottom and the front faces of Q as differential 1-forms evaluated at the cross product of vectors u, v in R³.
