苗菊博3809高中数学,立体几何中,点到平面的距离怎么算? -
狄饲邦19729473020 ______ 先求平面的法向量,然后过这一点和法向量求点到平面的垂线方程,再计算垂线和平面的交点,交点到那个点的距离就是点到平面的距离.

苗菊博3809(高考)在立体几何中,点到面的距离公式? -
狄饲邦19729473020 ______ 设面为AX+BY+CZ+D=0 点(X0,Y0,Z0)到面的距离公式为 d=\AX0+BY0+CZ0+D\/根号(A^2+B^2+C^2) 跟点到直线的距离公式差不多只是联系到空间,也是过该点分别作面的垂线,和斜线,组成直角三角形

苗菊博3809立体几何点到平面的距离公式
狄饲邦19729473020 ______ 立体几何点到平面的距离公式:d=|n.MP|/|n|.数学上,立体几何(Solid geometry)是3维欧氏空间的几何的传统名称—- 因为实际上这大致上就是我们生活的空间.平面,是指面上任意两点的连线整个落在此面上,一种二维零曲率广延,这样一种面,它与同它相似的面的任何交线是一条直线.是由显示生活中(例如镜面、平静的水面等)的实物抽象出来的数学概念,但又与这些实物有根本的区别,既具有无限延展性(也就是说平面没有边界),又没有大小、宽窄、薄厚之分,平面的这种性质与直线的无限延展性又是相通的.

苗菊博3809高中立体几何 求点到面距离方法 -
狄饲邦19729473020 ______ 用向量法来点到面的距离,把几何问题化归为代数问题,这种方法关键的是建立坐标系,找到面的法向量. 向量法:利用法向量与点到面距离关系,把几何问题转化为代数问题. 还有等体积法,转移法待续.

苗菊博3809空间立体几何中一个点到一平面的距离怎么算 -
狄饲邦19729473020 ______ 可以建立空间直角坐标系,在平面上任取一个点求出这两个点之间的向量,再求出平面的法向量,求出两向量夹角,用第一个向量的模乘夹角的余弦的绝对值就是点到平面的距离.

苗菊博3809立体几何中,点到平面距离的意思. -
狄饲邦19729473020 ______ 点到平面距离 =点到平面上最近的一点的距离 =过点向平面做垂线,垂线的长度 如果你站直了,你的头顶到地面的距离,也就是你的身高,就是一种点到平面的距离.

苗菊博3809在立体几何中,求点到面的距离各种方法. -
狄饲邦19729473020 ______ 三垂线法

苗菊博3809在作立体几何时有时碰到一点到平面距离.这距离如何算? -
狄饲邦19729473020 ______[答案] 过这个点作这个平面的垂线于平面的交点就是垂足,距离就是这点到垂足的长度.

苗菊博3809立体几何中点到平面距离公式中涉及到要设面为AX+BY+CZ+D=0 ,请问如果已知三个点,要怎么求这个面的表达式 -
狄饲邦19729473020 ______[答案] 整理一下这个方程 X+B/A+C/A+D/A=0 把这三个点的坐标代入这个方程,三个未知数,三个方程,正好可以解出B/A,C/A,D/A.

苗菊博3809请问立体几何中,线到面的距离如何计算我记得有一个公式,要用到法向量 -
狄饲邦19729473020 ______[答案] 连接线上一点和面上一点,所处他的坐标,再算出他的长度,求面的法向量,再算出刚才的直线与法向量的夹角,用刚才的直线的长度乘以这个角的余弦值即是线到面的距离
