什么叫scalar product of vector(向量的标量乘积?)还有就是有关以上类型的证明题.例如:平行四边形OACB.用a,b表示 OC,AB(上面有个方向符号).用标量乘积证明这个,如果平行四边形对角线相等,那它就是矩形. 相关知识点: 试题来源: 解析 就是向量的点乘=|a||b|cos(theta),theta是向量夹角.OC=a+bAB=b-a...

The cross product of the vectors = a_1,a_2,a_3 and = b_1,b_2,b_3 is the vector* =(vmatrix)& & & & & & (vmatrix)= __ + __ + __ So the cross product of = 1,0,1 and = 2,3,0 is * = __. 相关知识点:
A vector has magnitude (how long it is) and direction:Here are two vectors:They can be multiplied using the "Dot Product" (also see Cross Product).CalculatingThe Dot Product is written using a central dot:a· b This means the Dot Product of a and b...
Example 3.Find the dot product of vectorsp=a+ 3bandq= 5a- 3b, if their magnitudes is |a| = 3, |b| = 2, and the angle between the vectorsaandbis equal to 60˚. Solution: p·q= (a+ 3b) · (5a- 3b) = 5a·a- 3a·b+ 15b·a- 9b·b= ...
