Ratio Test

Подробнее о видео

This calculus 2 video tutorial provides a basic introduction into the ratio test. Examples include the ratio test with factorials, exponents, fractions, and square roots. If the limit of the ratio of next term with the previous is less than 1, the series converges. If it's more than 1, the series divergence. If the limit equals 1, the ratio test is inconclusive.
