Hihi all, just a short question that I need help in.
See the range of values for which (1+x)^-1 is valued for |x| < 1 right? Which means if we have an expression (1+2x)^-1, the values valid are |2x|<1 -> |x| < 1/2 right? However, what if I have (1+2x^2)^(3/2) instead?
Kindly enlighten me, thank you! :D
Hi,
We will have |2x^2| < 1.
In general, |second term| < 1so that the series converge.
Thanks!
Cheers,

Ahhh, I see, which means the power doesn't make a difference? :D Thanks!
As long as you expand in a way such that the terms are infinite, then you have to consider it...
which means the power cannot be a positive integer ;)
