Circular segment Circular segment In geometry, a circular segment (symbol: ⌓) is a region of a circle which is "cut off" from the rest of the circle by a secant or a chord. More formally, a circular segment is a region of two-dimensional space that is bounded by an arc (of less than 180°) of a circle and by the chord connecting the endpoints of the arc. Let "R" be the radius of the circle, "θ" the central angle in radians, α is the central angle in degrees, "c" the chord length, "s" the arc length, "h" the sagitta (height) of the
Basic symptoms of schizophrenia symptoms and brief transient psychosis, to detect at-risk mental states in help-seeking people. COPER criteria are met when at least 1 of the symptoms on the scale (see table below) is present with at least weekly occurrence in the last 3 months, and the first occurrence of symptoms was more than 12 months prior to evaluation.
