Infinite Sequences and Series (BC Only)
Which modification of an existing factor within Taylor Series expansion centered at x = a ensures its radius of convergence becomes zero?
Replacing factorial with raised to a higher power maintaining differentiability of f.
Increasing n by one in all terms while keeping f differentiable at x = a.
Making f non-differentiable at every point near x = a.
Decreasing x by half towards approaching limit near center 'a'.
Considering the alternating harmonic series , what alteration to the exponent on n would cause this series to diverge?
Changing the exponent on n from 1 to any number greater than or equal to one
Changing the exponent on n from 1 to exactly 2
Keeping the exponent on n as is without change
Changing the exponent on n from 1 to any number less than 1
What does it mean if an infinite geometric series has a ratio where ?
The series converges only if the first term is negative
The sum of the series equals infinity
The Series converges
The series does not have a sum
If the series is convergent, what can be said about the value of ?
If there exists a sequence such that for all , what do we know for sure about the sequence?
The sequence is a convergent sequence.
The sequence is a divergent sequence.
The sequence is a decreasing sequence.

If and are convergent series, is convergent or divergent?
is a convergent series.
It cannot be determined whether is convergent or divergent.
is a divergent series.
is neither convergent nor divergent
Which statement best describes a geometric series that has a common ratio of ?
It converges because
Not enough information is given to determine convergence or divergence without knowing the first term's value
It diverges because only ensures divergence for positive ratios
It diverges because
