Learn how to determine if two vectors are parallel, orthogonal or neither
Learn how to determine if two vectors are orthogonal, parallel or neither. You can setermine whether two vectors are parallel, orthogonal, or neither uxsing the dot/cross product or using the slope formula.
Recall that two lines are parallel if they both have the same slope and are perpemdicular/othorgonal is the slope of one of the lines is the negative of the reciprocal of the slope of the other line.
Also, if the scalar/dot product of two vectors gives zero then the two vectors are perpendicular/orthogonal but if the magnitude of the cross/vector product of two vectors is zero, then the two vectors are perpendicular.
