曲面的切平面方程
简单分析一下，答案如图所示
曲面的切平面方程是F'x(x0，y0，z0) (x-x0)+F'y(x0，y0，z0) (y-y0)+F'z(x0，y0，z0) (z-z0)=0。

平面方程是指空间中所有处于同一平面的`点所对应的方程，其一般式形如Ax+By+Cz+D=0，而曲面的切平面方程是F'x(x0，y0，z0) (x-x0)+F'y(x0，y0，z0) (y-y0)+F'z(x0，y0，z0) (z-z0)=0。绛旓細璁鏇查潰鏂圭▼涓 F锛圶锛孻锛孼锛夈傚叾瀵筙 Y Z鐨勫亸瀵煎垎鍒负 Fx锛圶锛孻锛孼锛夛紝Fy锛圶锛孻锛孼锛 锛孎z锛圶锛孻锛孼锛夈傚皢鐐癸紙a锛宐锛宑锛変唬鍏ュ緱 n锛濓蓟Fx锛孎y锛孎z锛 锛堝垏骞抽潰娉曞悜閲忥級銆傚啀灏嗗垏鐐癸紙a锛宐锛宑锛変唬鍏ュ緱銆鍒囧钩闈㈡柟绋Fx锛婏紙X锛峚锛夛紜Fy锛婏紙Y锛峛锛夛紜Fz锛圸锛峜锛夛紳0銆傦紙姹傚垏骞抽潰鏂圭▼鐨...
