(7) Let V be the region in R3 enclosed by the surfaces+2 20 and z1. Let S denote the closed surface of V and let n denote the outward unit normal. Calculate the flux of the vector field F(x, y, z) = yi + (r2-zjy + ~2k out of V and verify Gauss Divergence Theorem holds for this case. That is, calculate the flux directly as a surface integral and show it gives the same answer as the triple integral...
Let S2 denote the 2-dimensional sphere. Define the complex projective line 1 as the quotient space 2 \ {0} / ∼ , where ∼ is the equivalence relation on 2 \ {0} that x ∼ y if x = λy for some λ∈C.

Problem 3: Surface integral. 1. Determine the surface integral of the vector field v = xł over S = {r ER3 | x2 + y2 + z2 = RP, and x > 0, z>0} by projecting the surface S onto the region A of the xy-plane (see lecture notes). Show that you obtain the correct result using spherical coordinates. What quantity did you actually calculate? 2. Calculate the flux of vector A through the surface S, where S = {x...
Suppose that a scalar field is constant on a surface As shown in the lectures. there are two methods that one might use to obtain the normal to the surface, and they give the same direction (a) Let r(u, v) be a parametric form for the surface S. Use the vector identity to show that Our ar-λ▽u where λ is a scalar field. [Note: no marks will be awarded for simply stating that a term is zero. If it is...
I'll ask again, Please DON'T use the divergence theroem, I cant do the surface integral. (7) Let V be the region in R3 enclosed by the surfaces ++22,0 and1. Let S denote the closed surface of V and let n denote the outward unit normal. Calculate the flux of the vector field Fx, y, z)(2 - 2)j 22k out of V and verify Gauss' Divergence Theorem holds for this case. That is, calculate the flux directly as a surface integral...
Goal: Use integration to derive the volume of the solid sphere in dimensions above 3 (R4, Rʻ,...). Notation & Terminology: Use V, and S, for the "volume" and "surface area" of an n- dimensional solid sphere. Thus "Volume" is not always in cubic units, it is in units^n. So, similarly “surface area" is in units (n-1) and is the measurement of the boundary. 1. Look up & become familiar with the formulas for V, and S. Start in R', what...
