Today we are using the first derivative test to find the local maximum and minimum of a function and using the second derivative test to find the concavity and possible inflection points of the function.
In this example, we also discuss what we do when we end up with a one critical number. This problem would be in your calculus I class. Ben really steps it up with his ti 83 calculator and offers a lot of help. He is practically an equation solver. I know what you are thinking " help me with math" Well this problem is free tutoring so stay tuned and subscribe because I am hoping to have many more movies to watch. The movies will all be math related. Youtube videos will show how to do your problems so I will have many similar problems with as many possible variations as possible. This will be full episodes of worked out calculus problems.
