Prove that the vectors 3i –j – 2k & 2i -2j + 4k are orthogonal vectors.
Prove that the vectors 3i –j – 2k & 2i -2j + 4k are orthogonal vectors.
Let vector a = ( 3 , -1 , -2 ) , vector b = ( 2 , -2 , 4)
Consider vector a • vector b = 6 + 2 – 8 = 0
Therefore Therefore a and b are orthogonal vectors. a and Therefore a and b are orthogonal vectors. b are orthogonal vectors.
