Given the Cross Product , Find Angle Between Vectors

Thanks to all of you who support me on Patreon. You da real mvps! $1 per month helps!! :) / patrickjmt !! Given the Cross Product , Find Angle Between Vectors.
Here we are given the cross product of two unit vectors and we proceed to find the angle between two vectors.

AP Calc, Calc I, Calc II and now Statics: The classes that you have helped me through.
P.S. I got a 5 on the AP calc exam, but my university adviser talked me into retaking Calc I.

[@rupalisharma3424]

Are you studying this in university?

[@alxjones]

Most people don't cover vectors until Calc 3 or Physics 1 where I'm from, but you might see some basic vector algebra like this.

[@patrickjmt]

only if i actually tutored people...

[@shensley011]

I FUCKING LOVE PATRICK!!

[@jamesthibodeaux8277]

This was really helpful; Thank you! I'm starting to use your videos to help me in my physics class, well done!

How did you got theta=20.7 degree .

[@jayveemercader7742]

type shift+mode and set in degree (deg)

[@silveramai]

Thanks so much! This was super helpful.

[@ifaz2569]

Thanks bro!
I forgot the theory of the Cross prodect.

[@mostafa14141995]

why did you assume that the magnitudes for a&b are simply 1 ??

[@sebashemahlogonolo5042]

Mostafa Taha is every vector a unit vector?

[@jedhw4440]

@@sebashemahlogonolo5042 If yore calculating the angle between two vectors the magnitude of them doesn’t matter, so you can assume it's a unit vector. Not all vectors are unit vectors though

[@Alexj_movieguy]

The first line in the problem states “for unknown unit vectors a and b”. Unit vector magnitudes = 1.

im in my first trimester of trig/pre calc. will i be learning this?

[@ChristopherRangon]

Dude you are great!

[@Blindedbythelight]

Yo Patrick, I will fly you out to Philly to tutor me

[@2randomperson]

ok im taking physics next tri so i might as well try and learn this

[@coolgo1]

no not yet mate :)

[@rjxl8]

i love you man

[@sjsawyer]

He has!

[@Blindedbythelight]

oh lawd. couldnt even afford you for 30 min. you must be rich

[@kellyblakmoffat]

done

[@patrickjmt]

ok, $1000 per hour. 5 hour minimum
