Quick Revision Takeaways
Common Exam Pitfalls to Avoid
⚠️ Common Error: Assuming cross product is commutative: writing A x B = B x A.
✓ Correct Approach: A x B = - (B x A). Cross product is anticommutative because reversing order reverses the right-hand thumb direction.
Why: Direction flips 180 degrees according to the right-hand grip rule.
