The power rule for differentiation was derived by Isaac Newton and Gottfried Wilhelm Leibniz, each independently, for rational power functions in the mid 17th century, who both then used it to derive the power rule for integrals as the inverse operation. This mirrors the conventional way the related theorems are presented in modern basic ...
(5+7)/2 = 6. This makes sense, since the x^2 derivative at x=3 represents an angle midway between x=2 and x=4. It's the average of prior and latter tangents. Now consider x^3. At x=3, the derivative is 27. For x^3, x=2 is 8, x=3 is 27, and x=4 is 64. The tangent from 8 to 27 is 19; the tangent from 27 to 64 is 37.
Siegel's theorem improves this to an exponent about 2 √ d, and Dyson's theorem of 1947 has exponent about √ 2d. Roth's result with exponent 2 is in some sense the best possible, because this statement would fail on setting ε = 0 {\displaystyle \varepsilon =0} : by Dirichlet's theorem on diophantine approximation there are infinitely many ...
The distributions of a wide variety of physical, biological, and human-made phenomena approximately follow a power law over a wide range of magnitudes: these include the sizes of craters on the moon and of solar flares, [2] cloud sizes, [3] the foraging pattern of various species, [4] the sizes of activity patterns of neuronal populations, [5] the frequencies of words in most languages ...
The graph of the logarithm to base 2 crosses the x axis (horizontal axis) at 1 and passes through the points with coordinates (2, 1), (4, 2), and (8, 3). For example, log 2 (8) = 3, because 2 3 = 8. The graph gets arbitrarily close to the y axis, but does not meet or intersect it.

One can obtain explicit formulas for the above expressions in the form of determinants, by considering the first n of Newton's identities (or it counterparts for the complete homogeneous polynomials) as linear equations in which the elementary symmetric functions are known and the power sums are unknowns (or vice versa), and apply Cramer's rule ...
