The position vectors of the points A and B,relative to an origin O,are (3,4) and (k,2k) respectively.
Given that the magnitude of AB is 2,calculate the values of k.
矢量代数问题The position vectors of the points A and B,relative to an origin O,are (3,4) and (k,2k) respectively.Given that the magnitude of AB is 2,calculate the values of k.
(k-3)²+(2k-4)²=2².
5k²-22k+21=0.
(k-3)(5k-7)=0.
k1=3.k2=7/5.

矢量代数是怎么一回事
关于矢量计算问题在矢量计算中,代数时需不需要考虑方向,是不是不用管方向,直接带正数呢?
关于代数系统,代数常数概念的问题?例如V=这个1是代数常数,但是代数常数到底是个什么概念呢?
求矢量v加矢量u?
数学问题但要看的懂英语point A,B have position vectors a and b relative to origin O,where a=4i+3j-2k b=-7i+5j+4k find the angle OAB我翻译不好 大概意思是 矢量A B 有位置矢量a 和 b 和原点有关a=4i+3j-2k b=-7i+5j+4k 求角
