2. TL;DR: read bolded parts. Lets say I have f (x) = sin (x^2) and I want the f'''''' (0) (6th derivative). Using taylor series, this is really simple. We plug in x^2 into the taylor polynomial of sin (x), and get this: Then the 6th derivative is 1/3! * 6! = 120. I am confused because taylor series seems really unrelated; there should be an ...15 May 2018 ...

The second derivative is the rate of change of the rate of change of a point at a graph (the "slope of the slope" if you will). This can be used to find the acceleration of an object (velocity is given by first derivative). You will later learn about concavity probably and the Second Derivative Test which makes use of the second derivative.
