WebThus(1/x) (1/y) > 0 by definition of ordered field and by part (ii) (1/x) (1/y)x< (1/x) (1/y)y. By algebraic properties we get 1/y< 1/x. Product of two positive numbers (elements of an ordered field) is positive. However, it is not true that if the product is positive, then each of the two factors must be positive. WebFeb 17, 2024 · I would like to change the color of the Label associated to the "Edif field (Numeric)" element in the picture below. It does not appear in the ''COMPONENT BROWSER'' in the right panel. Is it possible?
