Is a function: “many to one“. This is saying if you have multiple x-values that map to one y-value — say, (2,9), (3,9) and (6,9) — then that still qualifies as a function. Put more simply, it’s okay for a function to have multiple coordinate points in a straight lin...
Zernike polynomialsare sets oforthonormal functionsthat describe optical aberrations; Sometimes these polynomials describe the whole aberration and sometimes they describe a part. For example, “myopia with astigmatism” could be described as ρ cos 2(θ). This description doesn’t quantify the aberratio...
On my view, this issue is connected to the literature on grounding (see the SEP entry by Bliss & Trogdon,2016). Epstein (2015) gives a uniform framework for modelling all these senses of grounding. He convincingly shows that all these senses may be modelled as a necessary implication, altho...

Specific types of parallelism There are distinct literary terms to describe literary devices that make up specific types of parallelism. Anaphora sets the stage by echoing words at the start of clauses, spotlighting them for emphasis, as in "In time we will prevail, in time we will be victor...
Their exponent “– 2/5” is very close to the exponent “-2/3” of Eq. (3) taking into account the fact that all approaches are approximate and can describe a certain time asymptotics. An important point is that Eq. (3) represents a rough approximation for the crystal velocity at ...
Higher-order terms (above the 4th) are difficult to estimate and equally difficult to describe in layman’s terms. For example, the 5thrmeasures the relative importance of tails versus center (mode, shoulders) in the cause of a distribution’s skew. ...
A distribution with a skewness of zero is symmetrical; any other number for skewness means that the distribution is asymmetric. That said, while we can use skewness to describe asymmetric distributions, there isn’t a rigorous mathematical foundation to establish what is meant by “kurtosis of an...
A price channel is achart patternthat graphically depicts the peaks and troughs of a security's price over a period of time. If there is an observable symmetry in the oscillation, then it is considered to be a valid price channel that can be used asa tool for stock analysis. Market tech...
