Find the Cross Product of Two Vectors (Easy Shortcut with i j k)

Is the matrix determinant method too much work? Need something simpler to calculate those pesky cross products? Or do you just want a consistent way to calculate them? If any of those are a 'yes,' then this video is for you.

Physics, engineering, math and even computer science all use cross products. If you’re studying in a STEM field, it’s very useful to know how to compute this.

Do you have another method you use to calculate cross products? Do you actually *like* finding the cross product with matrices? Maybe you have another neat math shortcut you use. Let me know in the comments! Stay tuned for more videos, too.

it complicates a lot the way I learned it back in the days… imagining a X on the other components: jxk for i, kxi for j, ixj for k… which is way simpler and faster!

thank you because this video is similar to our topic also

this is such an amazing explanation, it helped me so much.

What I don't get about some of this stuff is this.
Why does the vector coordinates have to be i, j, k why shouldn't they be x, y, z I mean vectors are an extension of the coordinate plane using x, y ... or why not make the base coordinate plane be i, j????

thank you but it is not shortcut for me because i think normal method is easy then your method.
I THINK ....
