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 ...
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...
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.
Learn how to determine whether two vectors are orthogonal to one another, parallel to one another, or neither orthogonal nor parallel. GET EXTRA HELP
Of course you can check whether a vector is orthogonal, parallel, or neither with respect to some other vector. So, let's say that our vectors have n coordinates. The concept of parallelism is equivalent to the one of multiple, so two vectors are parallel if you can obtain one from the other via multiplications by a number: for example, v=(3,2,-5) is parallel to w=(30,20,-50) and to z=(-3,-2,5...
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.

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).
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.
I am having some trouble finding parallel vectors because of floating point precision. How can I determine if the vectors are parallel with some tolerance? I also need a check for orthogonality with . ... How do I know if two vectors are near parallel. Ask Question 6. 3.
