→ ballistic; → trajectory.
Fr.: trajectoire isogonale
Math.: A curve which intersects every member of a given one-parameter family of curves at one and the same angle.
→ isogonal; → trajectory.
Fr.: trajectoire orthogonale
Math.: An → isogonal trajectory where the family of curves are cut at right angles.
→ orthogonal; → trajectory.
Physics: The line or curve described by an object moving through space.
From Mod.L. trajectoria, from feminine of trajectorius "of or pertaining to throwing across," from L. trajectus "thrown over or across," p.p. of trajicere "throw across," from L. → trans- "across" + icere, combining form of jacere "to throw," → eject.
Tarâyešâné, from tarâ- "across," → trans-, + -y- epenthetic + ešân, present stem of ešândan, → eject, + relation suffix -é.
