[微積] transformation問題
1.The region R is bounded by the planes 4x+y-2z=0,x-y+2z=0,y=0andx-y-3z+5=0.
use transformation x=u-3w,y=2v,z=2u+v+w to evaluate SSS(三重積分) y dV.
我將x,y,z代換後就不知道如何解題了...
2.
Find the length of the arc of the curve y=x^(3/2) from the point(1,1)to(4,8)
這題是曲線積分嗎?@@我只想到法向量(3,7)
y-x^(3/2)=0 去做偏微嗎...?感覺好像又不是...(對不起我不懂QQ)
