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))...
