WebApr 29, 2024 · To find proj v u, we first find the size of u's "shadow" on v (i.e. the scalar projection). This is a simple formula involving the dot product: (u • v) / v Here, u • v = (8) (7) + (7) (-1) = 56 - 7 = 49 and v = √ [7 2 + (-1) 2] = √50 = 5√2. So our shadow is (u • v) / v = 49 / 5√2 Next, we need to find the unit vector in the direction of v: WebAug 31, 2024 · There are a number of publications on relativistic objects dealing either with black holes or naked singularities in the center. Here we show that there exist static spherically symmetric solutions of Einstein equations with a strongly nonlinear scalar field, which allow the appearance of singularities of a new type (“spherical singularities”) …

WebWhat is projection of U on V? The distance we travel in the direction of v, while traversing u is called the component of u with respect to v and is denoted compvu. The vector parallel to v, with magnitude compvu, in the direction of v is called the projection of u onto v and is denoted projvu. Note projvu is a vector and compvu is a scalar. WebWouldn't it be nice if the length of v was 1. The length of v was equal to 1. If the length of v was 1, or this is another way of saying that, v is a unit vector. Our formula for our projection would just simplify to x dot v. All of that times, this …

Web1. Yes, the projection of u onto v can be 0. The projection of u onto v is the vector of the form λ v with smaller distance to u. So, asserting that the projection of u onto v is 0 simply means that of all vectors of the form λ v, the one which is closest to u is the one for which λ = 0. Geometrically, this means that u and v are orthogonal.
