If where is a polynomial with and positive leading coefficient, then is large.
Where the m are arbitrary positive coefficients.
This is a positive coefficient - that is, capacitance rises with a rise in temperature.
When "t" is negative, the fluctuations about the new minimum are described by a new positive quadratic coefficient.
Thus we derived where is a positive coefficient (see equation (4.14) above).
Income, Y, has a positive coefficient indicating that the good is a normal good.
The right branch of the unit hyperbola corresponds to the positive coefficient.
One may require all the polynomials to have positive leading coefficients, so that only a constant number of their values can be negative.
The difference between the sum of the positive coefficients and the sum of the negative coefficients should equal 1.
The Nine Chapters used red counting rods to denote positive coefficients and black rods for negative.
