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.
First-order neurons. This neuron pathway leads from the hypothalamus at the base of the brain, passes through the brainstem and extends into the upper portion of the spinal cord. Problems in this region that can disrupt nerve function related to Horner syndrome include: 1  Stroke. 2  Tumor. 3  Diseases that cause the loss of the protective sheath on neurons (myelin). 4  Neck trauma.
