intro tio the series

what is the ratio test.

• sin 0 - 1

• 2sinxcosx

What is the Divergence Test?

what is the sum formula?

for the divergence test what conditions must be met for a series to be convergent

• no conditions. the divergence test tests divergence NOT convergence!

• if the series is equal to 0

• if the series is equal to a number less than 1 but NOT in the negatives.

for the ratio test. what conditions must be met for the equation to be divergent

• if r is bigger than 1

• if r is smaller than 1

• if r is equal to 1

• if r is zero

what conditions must be met for convergence when using the ratio test?

• r is bigger than 1

• r is equal to 1

• r is zero

• r is smaller than 1
