FAQ

Q: What are series in Calculus II?
A: Series in Calculus II refer to the summation of an infinite sequence of terms.

Q: What is the nth term test for divergence?
A: The nth term test for divergence states that if the nth term of a series does not approach zero, then the series diverges.

Q: What is the integral test?
A: The integral test states that if a series has a corresponding improper integral that converges, then the series also converges.

Q: What is the comparison test?
A: The comparison test states that if a series can be compared to another series whose convergence is known, then the original series has the same convergence.

Q: What is the limit comparison test?
A: The limit comparison test states that if the limit of the ratio between the terms of a series and the terms of a known convergent series is a positive constant, then the original series has the same convergence.

Q: What is the ratio test?
A: The ratio test states that if the limit of the absolute value of the ratio between consecutive terms of a series is less than one, then the series converges.

Q: What is the root test?
A: The root test states that if the nth root of the absolute value of the terms of a series converges to a value less than one, then the series converges.

Q: What is the alternating series test?
A: The alternating series test states that if a series alternates in sign and the absolute value of its terms decreases monotonically to zero, then the series converges.

Q: What is the remainder estimation theorem?
A: The remainder estimation theorem provides a way to estimate the error in truncating a series to a finite number of terms.

Q: What is the Taylor series?
A: The Taylor series is a representation of a function as an infinite sum of terms that are calculated from the values of its derivatives at a single point.
