WebNote that since both u·v and v·v are scalars, so is u·v v· v. That scalar is then multiplied times v, resulting in a vector parallel v. if the scalar is positive the projection is in the direction of v, as shown in Example 4.2(b); when the scalar is negative the projection is in the direction opposite the vector being projected onto, as ... 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”) … Web( u − λ u) ⋅ v = ( 1 − λ) ( u ⋅ v) = 0. What you would want to do is the exact same thing, but suppose further more that x is co-linear to v, hence x = λ v, and solve for λ. Your idea was pretty good ; you were just missing one point. That does not classify as a hint though. bottom on top
