解析 Answer 1: It is given that, Now, we know that a⋅b=|a||b|cosθ ∴√6=√3*2*cosθ ⇒cosθ=(√6)/(√3*2) ⇒cosθ=1/(√2) ⇒θ=π/(4) π Hence, the angle between the given vectors a and is 反馈 收藏 ...
This example shows how you can find the angle between two vectors. The program has three main parts: selecting the points that define the vectors, drawing the vectors, and calculating the angle between them. The last task is the most important, but they're all interesting so I'll cover ...

【题目】Find the angle between the vectors. 相关知识点: 试题来源: 解析 【解析】|a|=√(4^2+(-3)^2+1^2)=√(26) |b|=√(2^2+0^2+(-1)^2)=√5and|a|⋅|b|=(4)(2)+(-3)(0)+(1)(-1)=7.,T,he ncosθ=(a⋅b)/(|a||b|)=7/(√(26)⋅√5)=7/(√(130))...
Angle between two vectors: In Vector Calculus, if {eq}\vec{a} \ and \ \vec{b} {/eq} are two vectors and {eq}\theta {/eq} is the angle between them, then Cosine of angle between vectors is equal to the dot product of two vectors divided by the magnitude of the two vectors tak...
If two vector quantities are coplanar, the angle between those two vectors can be easily obtained by means of graphical or geometrical methods. However, if the vectors are three-dimensional, then the analytical method is the most recommended....
