Standard explanation

Cyclic i->j->k->i. Opposite cycle gives a minus. These three lines are the exam memory: i x j = k, j x k = i, k x i = j.

Key points

• cyclic plus
• |a x b| = |a||b| sin theta
• direction: right hand
• a x b = - b x a
• I J K TABLE: Cyclic i->j->k->i. Opposite cycle gives a minus. These three lines are the exam memory: i x j = k, j
• i j k TABLE: Cyclic i->j->k->i.
• WHAT — I J K TABLE: Cyclic i->j->k->i. Opposite cycle gives a minus. These three lines are the exam memory: i x j = k, j
• WHY — Why it matters: This rule is a separate learning unit inside cross (vector) product. It can be defined, applied, and
