We explore a crucial aspect of Unit 10 in AP Calculus BC: the application of the ratio test for series convergence. One of the trickiest steps in utilizing the ratio test efficiently is the simplification of a substantial absolute value, a challenge we tackle head-on.

The ratio test involves calculating L, the limit of the absolute value of the ratio of consecutive terms in a series, as n approaches infinity. We start with a series a_n and proceed to find L by examining the limit of the absolute value, where the denominator is a_n (our original series term) and the numerator is a_(n+1), which we get by replacing n with n+1 in our series formula. Our goal for simplifying the big fraction is to break it into multiple fractions and simplify those individually, recombining them all later in order to streamline the expression.

I love how you explained things so throughly, thank you, I wish I could’ve find you a week ago when I had my Cal 2 final; Still passed with a A tho 😁😁
