The Second Derivative Test | Concavity, Extremas, Other Methods | Calc 1
How to use the second derivative test and see if a function is concave up or down, then to see if at that point you have a max or min.
Another easy way to find extremas, and is mainly useful when the first derivative test is a bit too messy. Thank you for watching this video, and I hope you enjoyed it or learned something from this!
Good luck in calc!
