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]

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 …

Aug 24, 2018 · A vector in 3-space is nothing more than the three numbers $ (x_1,x_2,x_3)$. We describe them as arrows because it helps with intuition. For example, the vector $ (1,1)$ can …

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?

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 …

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 …

Apr 15, 2017 · I've learned that in order to know "the angle" between two vectors, I need to use Dot Product. This gives me a value between $1$ and $-1$. $1$ means they're parallel to each …

Feb 16, 2013 · I know how to find the angle of using the dot product over magnitude of both vectors. However, these two vectors are opposite to each other, creating an angle of 180 …

Aug 7, 2017 · I am searching for an alternative method for solving for the angle between two vectors to verify my current solutions. the method I have currently used is the dot product, …
