Second Derivatives Flashcards

All 4 cards in this deck

What does d2ydx2\frac{d^2y}{dx^2} mean?

The derivative of dydx\frac{dy}{dx} — differentiate the function twice.

What does the second derivative measure?

The rate of change of the gradient function.

What notation is used for the second derivative of f(x)f(x)?

f′′(x)f''(x).

What are the steps to find d2ydx2\frac{d^2y}{dx^2}?
e.g. y=x3−3x2y = x^3 - 3x^2

  1. Differentiate once: dydx=3x2−6x\frac{dy}{dx} = 3x^2 - 6x
  2. Differentiate the result again: d2ydx2=6x−6\frac{d^2y}{dx^2} = 6x - 6
