WebJun 23, 2024 · sorry, its my mistake it should be of form y = f (x) not f (x) = 0. – user146551. Jun 23, 2024 at 13:36. Recall that -1 <= sin (x) <= 1 is true for all x. Use some algebra to work your way to the expression you want. Do this for each term. Then you should be able to find the max/min of your entire function. In computational chemistry, especially in QSAR studies, ovality refers to, a measure of how the shape of a molecule approaches a sphere (at one extreme) or a cigar shape (at the other). Ovality is described by a ratio of volume to area: where: O = Ovality A = Area V = Volume
WebIn telecommunications and fiber optics, ovality or noncircularity is the degree of deviation from perfect circularity of the cross section of the core or cladding of the fiber. The cross-sections of the core and cladding are assumed to a first approximation to be elliptical. Quantitatively, the ovality of either the core or cladding is expressed as, where a is the … Webpipes governed by vonmisses buckling equation - [15] or long pipes governed by Euler buckling equation [16].
