Math Hacks: Vectors - Memorizing Cross Product Formulas

#shorts

Hi there! In this video, we are covering techniques to remember the formulas for cross product! The first formula [ a x b = |a||b|sinθ(n) ] is easily remembered due to how similar it is to the dot product formula [ a x b = |a||b|cosθ ]! The second formula [ a x b = ([aybz - azby], [azbx - axbz], [axby - aybx]) ] is a bit trickier to remember, but in this video we cover a handy technique to use to help with this process!
