Infinite Summation: Define Tn & Find x,a Relationship

AI Thread Summary
The discussion focuses on defining Tn as the sum of the first n terms for given values of a and x, specifically within the range of 0 to 10. The equations provided detail how to calculate Tn using the formula Tn = (xlna)n/n!. A graphing calculator is suggested for visualizing the sequence, and it is noted that as n approaches infinity, the sum Sn approaches ax. The relationship between x and a is emphasized, with a connection to the exponential function e^x and its series expansion. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement



Define Tn as the sum of the first n terms, for various values of a and x, e.g. T9(2,5) is the sume of the first nine terms when a = 2 and x = 5.

The first n terms are 0-10, including both 0 and 10.

Homework Equations



T0=1, T1= (xlna)1/1, T2= (xlna)2/2!, T3= (xlna)3/3!... Tn = (xlna)n/n!


The Attempt at a Solution



Using a graphing calculator, seq(xlna)n/n!,n,0,10)

The relationship between x and a is: n --> infinity, Sn --> ax, Sn represents the sum of n.

I am not too sure what the question is but this seems like it might help


e^x=1+x+\frac{x^2}{2!}+\frac{x^3}{3!}+... = \sum_{n=0} ^{\infty} \frac{x^n}{n!}
 
I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
