[理工] [工數]-向量積分
Evaluate the integral ∫∫s F‧ndA by the divergence theorem,
where F=[x,y], S:z=2x+5y, 0< X <2, -1< y <1,
= = = =
and n is a unit normal vector of s
另外一題
Evaluate the line integral ∫F‧r'(s)ds by the Stoke's theorem
(clockwise as seen by a person standing at tje origin),
where F=[-5y,4x,z]; Cthe circle x^2+y^2=4, z=1;
r'=dr/ds is the unit tangent vector; s is the arclength os C
兩題算出來的答案都怪怪的
有沒有好心的高手指導我一下？
