The period goes INSIDE the parentheses ONLY if the entire sentence is enclosed in parentheses.
Example:
* (This is a complete sentence.)
However, if the parentheses contain a phrase or clause that is part of a larger sentence, the period goes OUTSIDE the parentheses.
Example:
* The dog ran to the park (his favorite place).
Here's a helpful way to think about it:
* Complete sentence within parentheses? Period goes inside.
* Part of a sentence within parentheses? Period goes outside.
