Chapter 6: Derivatives And Theorems Flashcards
Mean Value Theorem
For a function where you always have an instantaneous rate of change, the average rate of change will be equal to the instantaneous rate of change somewhere in the region where you’ve take the average.
Average rate of change
Total distance/total time
Instantaneous rate of change
Average rate of change at any specific time.
Rolle’s THeorem
A special case of the mean value theorem. If the average rate of change is zero, then the instantaneous rate of change equals zero somewhere along that path.
L’Hopital’s Rule
If you have some functions f(x) or g(x) that approach 0 as x->c
Lim. F(x)/g(x)=Lim f’(x)/g’(x)
x->c X->c
We do this if we get a limit=0/0.
L’hopitals Rule Part 2 with infinity
x->c goes to infinity for
Lim f(x)/g(x) =. Lim f’(x)/g’(x)
X->C. X->c
If lim F(x)=infinity
X->c
Lim. g(x)=infinity
X->c
This is used if limit=infinity/infinity
L’Hopitals 3-step plan
- Check limit of top & bottom
- Differentiate the top & bottom
- .Calculate limit of derivatives
