Finding vectors parallel to a given vector Physics Forums

WebIn general, the more two vectors point in the same direction, the bigger the dot product between them will be. When \theta = \dfrac {\pi} {2} θ = 2π, the two vectors are precisely perpendicular to each other. This corresponds to the dot product between them being 0 0, because \cos\left ( \dfrac {\pi} {2} \right) = 0 cos(2π) = 0. WebVectors a and b are always right angles to each other, so you can use the Pythagorean theorem to determine the magnitude (or length) of a+b. It is true that the angles between a and a+b or b and a+b can be any angle between (but not including) 0 and 90 degrees, but that doesn't matter when calculating the Pythagorean theorem.

WebIf θ = π , a. b = -ab [Two vectors are parallel in the opposite direction ⇒ θ = π.]. If θ = π/2, then a. b = 0 [Two vectors are perpendicular ⇒ θ = π/2] If 0 < θ < π/2, then cosθ is positive and hence a. b is positive. If π/2 < θ < π then cosθ is negative and hence a. b is negative. Other Properties of Dot Product WebNov 29, 2016 · a and b are parallel if a = κ b. Try MatrixRank [ {a, b}] == 1 for an easy way to test this. This works only if neither of the vectors have norm 0. Symbolic vector components (parameters) are considered independent by MatrixRank, so this method considers vectors parallel only if they are parallel for any value of the parameters.
