Wrath of Math | Infinite Series (-1)^n*(n^2/2^n) with Ratio Test | Calculus 2 Exercises @WrathofMath | Uploaded 1 week ago | Updated 4 hours ago
We determine the convergence of the series (-1)^n*(n^2/2^n) using the ratio test. We'll find the limit of the relevant ratio is less than 1, and so the series is absolutely convergent by the ratio test. This means also that it is plainly convergent. #calculus2 #apcalculusbc
