The word 'discriminant' is correct and usable in written English.
You can use it to refer to any difference between two or more things that is used to differentiate between them, such as discriminating between different types of behaviour. For example, "The judge used the defendants' past criminal records as a discriminant to determine the severity of the punishment."
Then he recorded the magnetic fluctuations of their brains.He analysed the results using a technique called discriminant function analysis.
A discriminant can be found for the general quadratic, or conic, equation ax2 + bxy + cy2 + dx + ey + f = 0; it indicates whether the conic represented is an ellipse, a hyperbola, or a parabola.
Primates are a homogeneous group morphologically, and it is only in the realm of behaviour that differences between primate taxa are clearly discriminant.
The following programming fragment employs the IF-THEN structure for finding one root of the quadratic equation, using the quadratic formula: The quadratic formula assumes that a is nonzero and that the discriminant (the portion within the square root sign) is not negative (in order to obtain a real number root).
The roots of a quadratic or cubic equation with real coefficients are real and distinct if the discriminant is positive, are real with at least two equal if the discriminant is zero, and include a conjugate pair of complex roots if the discriminant is negative.
The discriminant (symbolized by the Greek letter delta, Δ) and the invariant (b2 − 4ac) together provide information as to the shape of the curve.
Still, Mr Stammer's arrest illuminates the growing importance of facial-recognition technology.The two main techniques used to recognise faces electronically are principal-component analysis (PCA) and linear-discriminant analysis (LDA).
Discriminants also are defined for elliptic curves, finite field extensions, quadratic forms, and other mathematical entities.
The discriminants of differential equations are algebraic equations that reveal information about the families of solutions of the original equations.
Recent seismological work on treaty verification has involved using high-resolution seismographs in a worldwide network, estimating the yield of explosions, studying wave attenuation in the Earth, determining wave amplitude and frequency spectra discriminants, and applying seismic arrays.
In the meantime, some sort of rule is necessary, and testosterone appears to be the democracy of sex discriminants: the worst except for all the others.
