曲面积分 散度定理 求流量Flux integral:find the flux of the following vector fields across the given surface.Assume the vectors normal to the surface pount outward.F=r / |r|,r=<x,y,z>.across the sphere of radius a centered at the orig
The sphere is obtained by rotating the semicircle x=rcost y=rsint 0≤t≤π about the x-axis. Therefore, from Formula 6, we get S=∫_0^π2πrsint√((-rsint)^2+(rcost)^2dt =2π∫_0^πrsint√(r^2(sin^2t+cos^2t)dt=2π∫_0^πrsint⋅rdt =2πr^2∫_0^πsintdt=2π...
