For cubic equations in two variables, see cubic plane curve. Graph of a cubic function with 3 real roots (where the curve crosses the horizontal axisâwhere y = 0) (and hence no complex roots).n other words, a cubic function is defined by a polynomial of degree three. Setting Æ (x) = 0 produces a cubic equation of the form: Usually, the coefficients a, b, c, d are real numbers. However much of the theory of cubic equations for real coefficients applies to other types of coefficients (such as complex ones).
Neurosis (Boeree, 2006) is Karen Horneyâs theory about the ways in which people attempt to make life bearable for themselves. Unlike other theorists, Horney saw it as âcontinuousâ with normal life.
What a conceptâtake those ideas that the academics reject and make money off them. Particularly of note is the VALS Framework from Stanford Research Institute. VALS builds on Maslow's Holistic Dynamic Needs Hierarchy to segment the population by values, lifestyles, needs, beliefs, dreams, and points of view. This is what marketers call segmenting by psychographics, a highly effective tool for developing products and messages that appeal to our needs.
