- ProofProve in full detail that M2,2, with the standard operations, is a vector space.arrow_forwardIdentities Prove the following identities. Assume φ is a differentiablescalar-valued function and F and G are differentiable vectorfields, all defined on a region of ℝ3. ∇ x (F x G ) = (G ⋅ ∇) F - G (∇ ⋅ F) - (F ⋅ ∇)G + F (∇ ⋅ G)arrow_forwardmath Prove that f(x) = x ⋅ |x| is continuous at all points c in ℝ.arrow_forward
- Fundamental Theorem of Calculus. Suppose that g(x) is a differentiable function on [a, b]. Express g(b) − g(a) in terms of a function on the interior of [a, b].arrow_forwardProof that R3 = W1 ⊕ W2, where W1 = {(x1, x2, x3) : x1 + x2 + x3 = 0} and W2 = Lin(1, 1, 1). Lin - spacearrow_forwardTesting for conservative vector fields Determine whether thefollowing vector field is conservative (in ℝ2 or ℝ3). F = ⟨yz cos xz, sin xz, xy cos xz⟩arrow_forward
- Advanced Calculus: Use the Bolzano–Weierstrass Theorem to prove that if f is a continuous function on [a,b], then f is bounded on [a,b] (that is, there exists M > 0 such that |f(x)| ≤ M for all x ∈[a,b]). (Hint: Give a proof by contradiction.)arrow_forwardUsing basis and dimensions in vector space section for linear algebraarrow_forwardApplying the Fundamental Theorem of Line IntegralsSuppose the vector field F is continuous on ℝ2, F = ⟨ƒ, g⟩ = ∇φ, φ(1, 2) = 7, φ(3, 6) = 10, and φ(6, 4) = 20.

- Clairaut'sT heorem If fxy and fyx both exist and are continuous on a disk D, then fxy(a, b) = fyx(a, b) for all (a, b) E D.arrow_forwardFlow curves in the plane Let F(x, y) = ⟨ƒ(x, y), g(x, y)⟩ be defined on ℝ2. Find and graph the flow curves for the vector field F = ⟨1, x⟩ .arrow_forwardProof neat and clean handwriting ,Let T be a self-adjoint linear operator on an inner product space V. Then each characteristic value of T is real. Also if T is positive, or non-negative, then every characteristic value of T is positive, or non-negative, respectively.arrow_forward
