Power Series Problem: Determine Interval of Convergence

Click For Summary
SUMMARY

The discussion focuses on determining the series representation and interval of convergence for a power series related to the function involving the term [(-1)^n *(x/sqrt(6))^(2n+1] / (2n+1). The first four nonzero terms of the series were identified as (x/sqrt(6)) - (x^3/(3*6^(3/2))) + (x^5/(5*6^(5/2))) - (x^7/(7*6^(7/2))). The main challenge remains in calculating the interval of convergence, which requires analyzing the endpoints and applying convergence tests.

PREREQUISITES

a) Determine the series of the given function. In the first box after the summation symbol, type in -1 or 1 indicating whether the series is alternating or not.
b) Write out the sum of the first four nonzero terms of the series representing this function.
c) Determine the interval of convergence. The outside boxes require the endpoints and the inside boxes require the symbol < or <=.

I already got a.) which is sum from n=0 to infinity [ (-1)^n *(x/sqrt(6))^(2n+1) ] / (2n+1)
I think I got b.) not too sure if this one is right but i got (x/sqrt(6))-(x^3/(3*6^(3/2)))+(x^5/(5*6^(5/2)))-(x^7/(7*6^(7/2))).
And so I just need someone to check b for me and I don't even know what to do for the interval of convergence.
