What do we mean by the [second derivative] ? | For a function, (f), the derivative of its derivative |

Why are we even able to have the second derivative? | because the [derivative] is itself a function, we can calculate its derivative |

If we have [y = f(x)] How would we write its [second derivative] ? | we would write it as: (d^2y) / (dx^2) |

In general what does the [derivative] of a function tell us? | tells us whether a function is increasing or decreasing |

In general, what do we think of the [derivative] as? | we think of the derivative as a [rate of change] |

So what can we think of the [second derivative] as? | a [rate of change] of a rate of change |
