[@gauravnegi4312]

@@smoked8471 Cause he used i,j,k form to find dot products of vector. There are 3 forms of vector for example
3i+2j+5k (unit vector form, idk what's the exact name but i am calling this unit vector form)
(3,2,5) ( coordinate form)
(38^1/2) at any angle. (magnitude and angle form)
We use angle in the last case. Sir use the first case to represent vector therefore normal multiplication worked. In coordinate form we use matrix multiplication.
This might be not totally accurate but it should give a rough idea.

29:42 Another way to solve this is by finding X component and Y component and calculating tan α. Since the vector is i + j, both the components are 1. tan α = P/B = 1/1 = 1 = 45°.
