Show steps. WebThe elements of your sum follow a geometric rule. It happens that the sum of a geometric series has a simple formula (if P is not 1) : ∑ i = 0 n P i = P n + 1 − 1 P − 1 EDIT : Let's prove this ! ( P − 1) ( P n + P n − 1 +... + 1) = ( P n + 1 − P n) + ( P n − P n − 1) + ( P n − 1 − P n − 2) +... + ( P − 1) = P n + 1 − 1
Web$\begingroup$ You know that the power series itself converges inside the radius of convergence. What can you say about the formal derivative of that power series? If it converges, the term by term derivative is a valid differentiation of the function given by the power series. $\endgroup$ – WebPower series is a sum of terms of the general form aₙ (x-a)ⁿ. Whether the series converges or diverges, and the value it converges to, depend on the chosen x-value, which makes …
