Sep 29, 2022 · I know that the common approach in order to find an angle is to calculate the dot product between 2 vectors and then calculate arcus cos of it. But in this solution I can get an …

I would like to know if my way of solution is good. I have to find the angle between the vector [2,2] [2, 2] and [−1,2] [1, 2]

What would be a good definition of a signed angle between the vectors u and v? One possible definition is to define it by the rotation angle that applied to vector u results in a vector with …

Sep 24, 2019 · The definition of complex multiplication is multiply the magnitudes and add the angles. If you conjugate one of the numbers, that negates its angle. Can you take it from here?

Sep 4, 2018 · The angle between any two vectors with the same origin may be calculated using the dot product in Cartesian coordinates but since we just have unit vectors, we can simplify …

Dec 2, 2016 · If we have V x W = <2, 1, -1> (Cross-Product) and V ⋅ W = 4, (Dot Product) is it possible to find the angle between vectors V and W? Note that I do not actually know values …

Feb 24, 2018 · Translate your two vectors so that their tails are at the origin. Then draw a line through each of those two vectors. The smaller of the two angles is the called the "angle …

May 18, 2017 · Adding two unit vectors, vector addition, gives a resultant $\vec {c}$ that divides the angle between them. $ \vec {c}$ or any $\alpha \vec {c}$ are vectors that have this property.

Mar 31, 2014 · Computing the angle between two vectors using the inner product Ask Question Asked 11 years, 8 months ago Modified 1 year, 8 months ago

One way to find the angle is to represent the two vectors in the Euclidean coordinates and compute arccos of the dot product. Is there a simpler way? As pointed out in comments, is …
