The phrase "describe a trajectory" is correct and usable in written English.
It is commonly used in technical or scientific writing when discussing the path or course of something, such as the movement of an object or the progress of a process. Example: In his research paper, the scientist described the trajectory of the asteroid as it passed through the Earth's atmosphere.
As an additional example, in this manuscript we describe a trajectory-analysis Scoria script that colors the atoms of one protein chain by the frequency of their contacts with a second chain.
At the age of 15, Grant's brother Christopher began to experience grand mal convulsions that signalled a gradual decline in his mental and physical health; Grant describes a trajectory from "a blessed being who gladdened the heart of even the most miserable" to the "worst years of attrition" when, with each seizure, "a bit more of him was chipped away".
The bulk of this Article puts together the pieces of that history most relevant to an understanding of the law's historical forbearance, describing a trajectory of gatekeeping beginning with defamation and continuing to copyright infringement, including shifts in technology toward peer-to-peer networks, that has so far failed to provoke a significant regulatory intrusion.
By the Hamiltonian equations of motion, this point evolves in time, and thus describes a trajectory $x_t $
The memo describes a trajectory of improving energy efficiency by an additional 15 to 25percentt between now and 2050, while ramping up energy from renewable sources until it accounts for all or most of Boulder's electricity use.
The fourth and final cluster described a trajectory of high levels of primary care use decreasing sharply from 10to4.5.5 visits per year on average (High-decreasing).
In [26], we described a trajectory-oriented SLAM.
This corresponds to our "rising to high" adiposity trajectory 2. We describe a further trajectory 4 (rising to moderate adiposity) containing individuals not ultimately obese and therefore undetectable with dichotomized BMI, but nevertheless associated with high metabolic risk.
When stimuli are presented such that a particular sequence of appearance and disappearance occurs at the aperture boundary, subjects report that the line is rotating only; furthermore, the perceived centers of rotation appear to describe a cycloidal trajectory, even when one aperture shape is replaced by another.
