In the end, it's just symbols. Note that in physics, the mentioned convention is not used for members in arbitrary vector spaces, but only for vectors in physical 3D space, or sometimes in …

Apr 19, 2021 · Your notation $\mathbf {1}$ (or $\mathbf {1}^T$ if you insist that $\mathbf {1}$ is a column vector) is fine and is commonly used. Just define it when you are using it.

Question: Determine the angular acceleration of link AB and the linear acceleration of A for 0 = 90 degree if theta = 0 and theta = 3 rad/s2 at that position. Carry out your solution using vector …

Jun 5, 2019 · The vector police will be by to see you shortly. Using angle brackets like that is a gateway notational abuse and will lead to writing open intervals as $]0,1 [$ and the like.

1 Suppose I have a vector $\overrightarrow {a}$. If I wanted to describe its magnitude, there's a standard notation for that, $\lVert\overrightarrow {a}\rVert$. Is there a standard notation for its …

A positive charge q is fixed at point (3,-4) and a negative charge - is fixed at point (3,0). Determine the net electric force Fnet acting on a positive test charge + at the origin (0,0) in terms of the …

Oct 29, 2020 · a line over a variable has established meaning in other contexts, so it might be good to use different notation. But notation is only notation; if its only for your eyes, then you …

Jun 2, 2015 · In the video, at that very time, the speaker explains he is using that notation to point out $\hat {u}$ is a unit vector, i.e. a vector of norm $1$. This sort of notations (once explained) …

Is there a notation for element-wise (or pointwise) operations? For example, take the element-wise product of two vectors x and y (in Matlab, x .* y, in numpy x*y), producing a new vector of …
