推 joecheng:第一題用橢球座標 跟球座標類似 140.116.113.19 06/12 15:36
1.
Let R be the region inside the ellispsoid x^2 y^2 z^2
___ + ___ + ___ = 1
a^2 b^2 c^2
where a.b.c>0,and above the plane z=b-y,then the volume of region R is ___
2.由曲面(x^2+y^2)^1/2 + z =1 ,和兩平面x=z, x=0所為體積____
--------------------------------------------------------------
積分區域都取不太出來,哭哭~
希望有人可以hint一下
