Question

Calculate the value of I cap cross I cap​

Answer 1

The value of i cap × i cap is equal to 0.

Explanation:

In this case, we need to find i\times ii×i . We know that the angle between two vectors in terms of cross product is given by :

A\times B=|A||B|\ sin\thetaA×B=∣A∣∣B∣ sinθ

Where

\thetaθ is the angle between A and B

If we want to find i\times ii×i , the angle between them is 0

So,

i\times i=|i||i|\ sin(0)i×i=∣i∣∣i∣ sin(0)

Since, sin(0)=0sin(0)=0

So, i\times i=0i×i=0

Hence, the value of i cap × i cap is equal to 0.
