To solve the problem, we need to find the value of n such that the coefficients of the 14th, 15th, and 16th terms in the expansion of (1+x)n are in Arithmetic Progression (A.P.). 1. Identify the Terms: The r-th term in the expansion of (1+x)n is given by: Tr=(nr−1)...
The authors propose a method to estimate operational variables of power system by use of higher order Taylor series after transmission line is out of operation, the advantage of this method lies in that the admittance matrix is not to be re-factorized after one branch is out of operation and...
A Taylor series of a function f (x) around a value a is given by (Eq. 4.1)f(x)=f(a)+11!df(a)dx(x−a)1+12!d2f(a)dx2(x−a)2+13!d3f(a)dx3(x−a)3+⋯=∑n=0∞1n!dnf(a)dxn(x−a)n (Eq. 4.2)=∑n=0nmax1n!dnf(a)dxn(x−a)n+On,max Obviously, the ...
接下来让我们看下“extension”和“expansion”的其他区别：方法和手段：extension通常是通过某种技术、工具或方法来实现延伸或扩展，如专利延期、宽带互联网接入等。expansion则通常涉及资源的投入、设施的建设或人员的增加等。例如：The city's extension of its subway system will require significant ...
If the values if n extend to -∞, then f(z) has an essential singularity at z0. In the special case that all the coefficients a-n vanish, we have a Taylor series for f(z) and f(z) is analytic in the neighborhood of z0. It is not necessary that the expansion point of a ...

To solve the problem, we need to find the value of n given the binomial coefficients of three consecutive terms in the expansion of (1+x)n are 220, 495, and 792. 1. Identify the Terms: Let the three consecutive terms be represented as: - First term: (nr−1)=220 - Second term:...
