Match each series to the test that should be used to test for convergence/divergence. While it is possible that each test could apply to more than one series, in this exercise each is only used once. [infinity]

a. ∑2^n/n!

n=1

[infinity]

b. ∑n^2

n=1

[infinity]

c. ∑(-1)^n+1 (n+1)/(3n+1)

n=1

1. Alternating series.

2. Geometric series.

3. Ratio test.

4. nth term test.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
