2018 L’Hopital’s Rule

BC Calculus


Finding limits
FINDING LIMITS

Rem: Always start with Direct Substitution

Method 1: Algebraic - Factorization

Method 2: Algebraic - Rationalization

Today

is

the

Day!!!

Method 3: Numeric – Chart (last resort!)

Method 4: Calculus

To be Learned Later !

If produces the Indeterminant Form,( or ),

then

Provided the limit exists and . (Also )

L’Hopital’s Rule

CAUTION: Think of this as the comparison of two functions

NOT a Quotient Rule << NOT Bo-d(To) >>
