<p>Thank you very much! Your explanations are very clear.</p>
<p>I’m still a bit confused about the relationship between geometric series and power series. One of the resources I’ve been using ([Power</a> Series](<a href=“http://www.sosmath.com/calculus/powser/powser01.html]Power”>Power Series)) implies that there’s a relationship between the two (to be honest, I’m not able to follow their logic entirely). Does such a relationship only exist in special cases?</p>
