In Exercises 3鈥�8, let A, B, C, D, ... , Z be points in R3. Simplify the given quantity.

role="math" localid="1663305327547" AB鈫�+BA鈫�

Short Answer

Expert verified

AB鈫�+BA鈫�=0

Step by step solution

01

Given

AB鈫�+BA鈫�

02

Simplify

As we know, the negative sign of any vector will change the direction of any vector.

BA鈫�=-AB鈫�

AB鈫�+BA鈫�=AB鈫�-AB鈫�=0
