A vertex represents a point of interaction: either EM, weak or strong. The strength of the interaction is denoted by g EMinteraction: g = Qe (sometimes denoted as Q √ α, where α= e2/4π) Weakinteraction: g = g W Stronginteraction: g = √ α s A vertex will have three (in rare cases four) lines attached, e.g. e+ e Qe e Qe e Qe e e e e+ Qe

The line passing through the center of the sphere and attaching to the mirror is known as the principal axis. The point in the center of the sphere is the center of curvature. The point on the mirror's surface where the principal axis meets the mirror is known as the vertex.
For standard form: y=Ax^2+Bx+C. Look at the coefficient of the x^2 term. If "A" is positive, the parabola opens up. If "A" is negative, then the parabola opens down. For Vertex Form: y=a (x-h)^2+k. The sign of "a" determines the direction of the parabola. If "a" is positive, the parabola opens up.

- I use a tactic that I found online - If its positive, it looks like a smile! if negative, it looks like a frown! Its actually quite handy if you as...
- It is 1, because in math, everything is already inherently being multiplied by 1. There *is* a coefficient, it is one.
- Hello! The "method" I was taught, was really just doing the algebra as follows: Finding the vertex of the quadratic by using the equation x=-b/2a,...

- You can tell from the quadratic term, the value of A in `y = Ax^2 + Bx + C` or `y = A(x - H)^2 + K`. If A is positive, the graph expands upward (we...
- I think it would, because it would indicate how the parabola is graphed.

- 1) Make the function look like ax^2 + bx + c = 0. 2) Use the vertex formula to find it. x = -b / 2a 3) Use the x value to find the y value. Hope th...
- you can use the quadratic equation or by completing the square to solve it, but you need to be more specific of what type of help you need
Sep 12, 2022 · A ray that strikes the vertex of a spherical mirror is reflected symmetrically about the optical axis of the mirror (ray 4 in Figure \(\PageIndex{5}\)). We use ray tracing to illustrate how images are formed by mirrors and to obtain numerical information about optical properties of the mirror.
Apr 8, 2021 · there are two vertices. The first vertex is of the incoming two electrons, the second vertex of the outgoing two electrons. In this generic Feynman diagram: There are four vertices,two secondary.This is a higher order diagram. Depending on the interaction under study , the last vertex in this Feynman diagram may be used to model two jets, jets ...
