Infinite summation
1. The problem statement, all variables and given/known data
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 010, including both 0 and 10.
2. Relevant equations
T0=1, T1= (xlna)/1, T2= [(xlna)^2]/2!, T3= [(xlna)^3]/3!.... Tn = [(xlna)^n]/n!
3. 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.
In order to "define" it, should I simply put the equation into summation notation or is it looking for something else?
