WebOct 23, 2024 · I know that two vectors are parallel if B − A = c ( P − Q). If c is greater than zero, then two vectors point at the same direction, while if c is smaller than zero, then they point at the opposite direction. However, I fail to see how these two vectors are parallel.

WebDec 29, 2024 · When the angle between →u and →v is 0 or π (i.e., the vectors are parallel), the magnitude of the cross product is 0. The only vector with a magnitude of 0 is →0 (see … WebTwo vectors A and B are parallel if and only if they are scalar multiples of one another. A = k B , k is a constant not equal to zero. Let A = ( Ax , Ay) and B = ( Bx , By ) A and B are parallel if and only if A = k B ( Ax , Ay) = k ( Bx , By) = ( k Ax , k By ) …

WebTwo or more vectors are said to be parallel vectors if they have the same direction but not necessarily the same magnitude. The angles of the direction of parallel vectors differ by zero degrees. The vectors whose angle of direction differs by 180 degrees are called antiparallel vectors, that is, antiparallel vectors have opposite directions.
