Why are two vectors multiplied vertically equal to 0 A*b=|a*|b|*cosαWhen the angle is 90 degrees,|a*|b|*cosα=0, but why does a*b have to be 0, and a*b isn't 0? Can't ╮()) Why are two vectors multiplied vertically equal to 0 A*b=|a*|b|*cosαWhen the angle is 90 degrees,|a*|b|*cosα=0, but why does a*b have to be 0, and a*b is not 0? Can't ╮())
A*b=|a b|* cos (a, b angle), this is the definition. a, b perpendicular to the cos (a, b angle)=0, so a*b=0
