The Method of Mechanical Theorems convenient to use a little bit of coordinate geometry. If a sphere of radius 1 is placed with its center at "x" = 1, the vertical cross sectional radius formula_2 at any "x" between 0 and 2 is given by the following formula: The mass of this cross section, for purposes of balancing on a lever, is proportional to the area: Archimedes then considered rotating the triangular region between "y" = 0 and "y" = "x" and "x" = "2" on the "x"-"y" plane around the "x"-axis, to form a cone. The cross section of this cone is a circle
4-D (The X-Files) creative team has a legitimately cool concept: it wastes the opportunity." M.A. Crang, in his book "Denying the Truth: Revisiting The X-Files after 9/11", felt that the interactions between Robert Patrick and Annabeth Gish were the "highlights" of the episode, but he was critical of the ending for wrapping things up "far too conveniently." 4-D (The X-Files) "4-D" is the fourth episode of the ninth season and the 186th episode overall of the American science fiction television series "The X-Files".
