Let m be the closed surface that consists of the hemisphere
m1: x2 + y2 + z2 = 1, z = 0,
and its base
m2: x2 + y2 = 1, z = 0 .

let e be the electric field defined by e = (18 x, 18 y, 18 z). find the electric flux across m. write the integral over the hemisphere using spherical coordinates, and use the outward pointing normal.

(( a c
))m1 e ·ds = ((
)) f) d? df
b d
where

a = pi/2, b =0 , c =2pi , d =0 ,

using t for ? and p for f,
f) = ? ?

((
))m1 e ·ds =

((
))m2 e ·ds = 0 , so

((
))m e ·ds =

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
