The answers about using the cross product are correct, but needlessly complicated. If two vectors are parallel, then one of them will be a multiple of the other. So divide each one by its magnitude to get a unit vector. If they're parallel, the t...

Tell whether the following two vectors are perpendicular or parallel and why. Perpendicular, because their dot product is zero. Perpendicular, because their dot product is one. Parallel, because their dot product is zero. Neither perpendicular nor parallel, because their dot product is neither zero ...

They are parallel if and only if they are different by a factor i.e. (1,3) and (-2,-6). The dot product will be 0 for perpendicular vectors i.e. they cross at exactly 90 degrees. When you calculate the dot product and your answer is non-zero it just means the two vectors are not perpendicular.

If the two vectors are in the same direction, then the dot product is positive. If they are in the opposite direction, then the dot product is negative. If A and B represent two vectors, then the dot product is obtained by A.B. cos q, where "q" represents the angle between the two vectors. Thus, if the vectors are anti-parallel, q equals 180 ...

To find a unit vector parallel to another vector you must find the magnitude of the vector and divide its components by the magnitude. Vector a = 3i + 6j + 2z ... Are The Two Vectors Parallel ...

The dot product gives us a very nice method for determining if two vectors are perpendicular and it will give another method for determining when two vectors are parallel. Note as well that often we will use the term orthogonal in place of perpendicular. Now, if two vectors are orthogonal then we know that the angle between them is 90 degrees.

Question 2 Find the real number a so that the vectors A = (2a , 16) and B = (3a+2 , -2) are perpendicular Solution to Question 2 The condition for two vectors A = (Ax , Ay) and B = (Bx , By) to be perpendicular is: Ax Bx + Ay By=0 Rewrite the above condition using the components of vectors, we obtain the equation

Two vectors are parallel if they have the same direction or are in exactly opposite directions. Now, recall again the geometric interpretation of scalar multiplication. When we performed scalar multiplication we generated new vectors that were parallel to the original vectors (and each other for that matter).
