A power series in 'x' involves factors where an 'X' is added to a constant, and raised to a power, forming infinite terms. Learn how to build a...
In this lesson, we find the power series for ln(1 - x) by deriving a simpler series and then integrating it. This lesson includes how to find the...
Produce a power series for y=ln(x+1) Power series expansion of functions:We can produce a power series for an infinitely differentiable function f(x) defined on some disk of radius 'R', centred at 'a'. It's given by, f(x)=f(a)+f′(a)1!(x−a)1+f″(a)2!(x−a)2+f...
f(x)=∑n=0∞=? Determine the interval of convergence. (Enter your answer using interval notation.) Power Series Representation : Here we will use some basic tools such as Algebra and Geometric Series in order to determine the power series representation of the...
We will look for solutions of Eq. (1) as formal power series with real exponents. We restrict ourselves to the Hahn field\(\mathbb {C}((x^{\mathbb {R}}))\)of generalized power series, that is, formal power series of the form\(\sum _{\gamma \in \mathbb {R}} c_{\gamma }x...

applying either of the transfor mations xi=Ti(Xi)=XiQi, where Qi < 0, or xi = Ti(Xi) =exp(Xi) to any variables xi with positive powers in the term, as long as the inverse transformations Xi=Ti-1(xi)=xi1/Qi and Xi=Ti-1(xi)=ln(xi) respectively, are approximated by PLFs X...
LN), Jilin (JL), Shanxi (SX), and Hebei (HE), ranging from 8.0 to 11.3% and 5.3 to 13.6%, respectively. These two areas account for 25.0% and 27.9%, respectively, of the total prediction error in China. Regarding solar energy, the prediction error is concentrated in the areas of ...
\int_{0}^{1}\frac{(\ln{x})^2}{1+x^2}dx=2(\frac{1}{1^3}-\frac{1}{3^3}+\frac{1}{5^3}-...) 后面是一个很well-known的级数,可以用Fourier series做出来,结果是 \frac{\pi^3}{32} ,所以: \int_{0}^{1}\frac{(\ln{x})^2}{1+x^2}dx=\frac{\pi^3}{16} 上次...
