A: If the limit is 1, the ratio test is inconclusive, and other tests should be used to determine convergence.

  • To use the ratio test, we take the absolute value of the ratio of consecutive terms in a series: |a_n+1 / a_n|

    The ratio test is a valuable tool in calculus, and understanding when to use it is crucial for success. By learning more about the ratio test and its applications, you can stay ahead of the curve and make informed decisions in your academic and professional pursuits.

    The ratio test is a simple yet effective method to determine the convergence of a series or sequence. It involves taking the limit of the absolute value of the ratio of consecutive terms. If the limit is less than 1, the series converges. If the limit is greater than 1, the series diverges. If the limit is 1, the test is inconclusive.
