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 ...
