A power series is an infinite polynomial on the variable x and can be used to define a variety of functions. Explore the formula and examples of power series, discover recommendations and suggestions for using it, and learn about the geometric series. ...
to the Riemann sphere. Such functions are known asmeromorphic functions, and are nearly as well-behaved as holomorphic functions in many ways. In fact, in one key respect, the family of meromorphic functions is better: the meromorphic functions on turn out to form a field, in particular the ...
Find the Taylor polynomial T_n(x) for the function f at the number a. Graph f and T_3. f(x) = xe^(-5x), a = 0, n = 3. Find the Taylor polynomial T_n(x) for the function f at the number a. Graph f and T_3. f (x) = 9 x + e^{-4 x}, a = 0, n = 3...
for any polynomial that vanishes on the coordinate hyperplanes . The right-hand side can also be evaluated by Mertens’ theorem as when is odd and when is even. Using the Weierstrass approximation theorem, we then have for any continuous function that is compactly supported in the interior of ...
It is not too hard to show that complex numbers yield a consistent theory, in the sense that when you add them, subtract them, multiply them, or divide them, you get a complex number back as the result of the operation. Furthermore, it turns out that all p...
Therefore the result of a floating-point calculation must often be rounded in order to fit back into its finite representation. This rounding error is the characteristic feature of floating-point computation. The section Relative Error and Ulps describes how it is measured. ...

This polynomial is call the s Draw a graph from the following data. Draw tangents at x = 2, 4, 6 and 8. Find the slopes of these tangents. Verify that the curve drawn is y = x^2 and the slope of tangent ...
Local wave activity (LWA) measures meandering of the jet stream, large values often linked to disruptions of the jet and extreme weather Observed probability distribution of LWA is positively skewed due to nonlinearity in the zonal advection (LWA-zonal wind interaction) Frequency of large LWA events...
Also, the computation of the relative odds of two competing hypotheses and can become somewhat moot if there is a third hypothesis that ends up being more plausible than either of these two hypotheses. Nevertheless, the formula (1) can still lead to useful conclusions, albeit ones that are ...
