Find the angle between the vectors of i+2j-3k ,3i-j+2k

Answer»

ANSWER: If a = i+2j-3k and b = 3i-j+2k, then the ANGLE between the VECTORS a+b and a-b is? Since, the product of two vectors (a+b) and (a-b) is zero. Therefore, they are perpendicular to each other and the angle between them is 90 degrees.
