Remember that all previous algebraic “rules for limits” are still valid. Try to “plug in” the “target value” – watch for undefined terms and “”. Write all functions in terms of sin or cos. Algebraically manipulate the function to look for a “replacement function”. Work towards the 2 “special limits” and Examples: 1. 2 ...
