Are the vectors a {-3; 1; -1} and b {4; 0; -12} perpendicular
| March 1, 2021 | education
1) Let’s calculate the dot product of these vectors: a * b = (-3) * 4 + 1 * 0 + (-1) * (-12) = -12 + 0 + 12 = 0.
2) We got that the scalar product of vectors a and b is equal to zero. This means that these vectors will be perpendicular.
ANSWER: yes, they are perpendicular.
