Rolle’s Theorm
Let f be a function that is CONTINUOUS on the CLOSED INTERVAL [a,b] and DIFFERENTIABLE on the OPEN INTERVAL (a,b). If f(a) = f(b), then there is at least one number c in (a,b) such that f’(c)=0.
MVT
AROC=IROC
EVT
If f is continuous on a closed interval [a,b], then f has BOTH a maximum and a minimum on the interval
Critical numbers
F’(c)=0 or if f is not differentiable at c
The Second Derivative Test
f’(c)=0
If f”(c)>0, then f(c) has a relative minimum
If f”(c)<0, then f(c) has a relative maximum
Rate of change between two equations
R(t)= f(t)-g(t)
T=time
Indeterminate forms that require l’hospitals
(0/0), any mix of infinities
L’hospital’s rule
The lim as x approaches c (f(x)/g(x)) is equal to the limit as x approaches c (f’(x)/g’(x))
