Please how did you get the 3 root 2(3√2) ?

[@SkanCityAcademy_SirJohn]

Okay.
From the last but one step, we had root (18)
So root (18)
= root of (2*9)
= root of (2) * root of (9)
Root of (9) = 3
Hence
= 3*root of (2)

The arrows on a vector represent the sense and not the direction which is given by the angle it subtends with a particular reference line. The initial point is known as the tail and the terminal point as the head of the vector. The video did not explain the unit vectors namely i, j and k.

[@SkanCityAcademy_SirJohn]

Thanks so much for your input.
Unit vectors are discussed in the subsequent lessons.

[@gamerace8524]

Bro what does i and j stand for??????

[@SkanCityAcademy_SirJohn]

i and j are unit vectors along the x and y axis respectively

[@reedib5758]

What's I and j???

[@SkanCityAcademy_SirJohn]

I and j are unit vectors along the X and y axis respectively
