推 GBRS:第二題有點怪怪的...既然要求方向導數... 211.76.47.253 07/16 17:53
→ GBRS:就應該有個方向向量...難不成是任意的? 211.76.47.253 07/16 17:54
推 puppy110330:應該可以自己求出方向向量 140.134.220.19 07/17 12:03
1.use the double integral to find the volume of tetrahedron bounded by the
planes x+y+z=1 x=0 y=0 z=0
2.let F(x.y)=ln(y/x) find themaximum value of directional derivative of f
at the point (4.2)
3.find the limit lim(1/n+1 + 1/n+2 +...........+ 1/n+n)
n->00
4.the tangent line of F(x.y)=x^3-2x^2+x+1 is parallel to y=5x+3
at x=?
5.a linear approximation of f(x)=(x+3)^1/2 at a=1 is??????
