Exam (elaborations) TEST BANK FOR Manifolds, Tensor and Forms An Intro 6 Let v1, v2 ∈ ker T . Then T (av1 + bv2) = aT v1 + bT v2 = 0, so ker T is closed under linear combinations. Moreover ker T contains the zero vector of V. All the other vector space properties are easily seen to follow, so ker T is a subspace of V. Similarly, let w1, w2 ∈ im T and consider aw1 + bw2. There exist v1, v2 ∈ V such that T v1 = w1 and T v2 = w2, so T (av1 + bv2) = aT v1 + bT v2 = aw1 + bw2, which show...

Exam (elaborations) TEST BANK FOR Microeconomic Analysis 3rd Edition B 1 False. There are many counterexamples. Consider the technology generated by a production function f(x) = x2. The production set is Y = {(y, −x) : y ≤ x2} which is certainly not convex, but the input requirement set is V (y) = {x : x ≥ √y} which is a convex set. 1.2 It doesn’t change. 1.3 1 = a and 2 = b. 1.4 Let y(t) = f(tx). Then dy dt = Xn i=1 ∂f(x) ∂xi xi, so that 1 y dy dt = 1 f(x) X...

Exam (elaborations) TEST BANK FOR Introduction to Solid State Physics The vectors xˆ ˆ + + y zˆ and − −xˆ yˆ + zˆ are in the directions of two body diagonals of a cube. If θ is the angle between them, their scalar product gives cos θ = –1/3, whence . 1 cos 1/ 3 90 19 28' 109 28' − θ = = ° + ° = ° 2. The plane (100) is normal to the x axis. It intercepts the a' axis at and the c' axis at ; therefore the indices referred to the primitive axes are (101). Similarly,...
