Final answer:
The dot product can be used to determine whether two vectors are perpendicular. If the dot product of two vectors is zero, then the vectors are perpendicular.
Step-by-step explanation:
The dot product can be used to determine whether two vectors are perpendicular. If the dot product of two vectors is zero, then the vectors are perpendicular. The dot product is calculated by multiplying the corresponding components of the vectors and then summing them up.
For example, if we have two vectors A = (3, 2) and B = (-2, 3), we can calculate their dot product as:
A · B = (3 * -2) + (2 * 3) = -6 + 6 = 0
Since the dot product is zero, we can conclude that vectors A and B are perpendicular.
