Limit of a sequence

First, rearrange it to:
Then take the natural log of both sides to get:
lim ln(an+b)/n=0
This goes to ∞/∞, which is an indeterminate form and ripe for L'Hopital's rule. | {"url":"http://www.physicsforums.com/showthread.php?t=3335","timestamp":"2014-04-18T21:31:43Z","content_type":null,"content_length":"34288","record_id":"<urn:uuid:6679025e-200c-450b-803e-88581591fd6a>","cc-path":"CC-MAIN-2014-15/segments/1398223206120.9/warc/CC-MAIN-20140423032006-00022-ip-10-147-4-33.ec2.internal.warc... |

MATH 308 Project: D-Orbitals
d-Orbitals are more complex wavefunctions than either s or p orbitals. Each of the five has a dependency on all three variables. However, they can be converted to Cartesian equivalents as in the
