True-False Quiz Questions 5 to 7: Rearranging Vectors in the Dot and Cross Product

▶️ Watch on 3Speak

---

In this video I rearrange the vectors in the dot product and cross product and show that we get the same answer for the dot product but the negative value for the cross product. When taking the length or the magnitude of the cross product, then the length is the same when vectors are rearranged since we do not need to know the direction for this case.

Time stamps:

• Question 5: Dot product can rearrange vectors: 0:00
• Question 6: Cross product gives negative result when rearranging vectors: 2:07
• Question 7: Length of cross product is the same when rearranging vectors: 3:50
