[@Ibrahim_Ezzeddine]

Does not make any sense isn't should be a square equal OL square plus LA square isn't pythagorean theorem

[@aarzenff]

Its not Pythagorean theorem 😂 Teacher used triangle law property.....

[@bartarajpyakurel5406]

Why we take b^ * a^ why not a^ * b^ ?

[@BrightTuition]

Then we will get negative vector Then we should take perpendicular as negative Then cancel the negative sign both sides

[@sugan2005]

Super sir

[@BrightTuition]

Thanks

[@techwave5239]

Why A coordinates are cos alpha sin alpha?

[@BrightTuition]

In unit circle x axis cos, y axis sin, because cos 0 is 1 and sin 90 is 1

[@techwave5239]

@@BrightTuition and why are they always unit vector in this proof

[@techwave5239]

5:10 how we can write OL vector as cos alpha i cap🤯😵

[@techwave5239]

10:46 k cap perpendicular vector?
