The Chain Rule - Version 1
|
Let "y" be y=F(u) where u = u(x).
Then y '(x) dy/dx = (dy/du) / (du/dx) |

Let F(x) = f(g(x))
Then F '(x) = f ' (g(x))(g'(x)) |

Steps for Implicit Differentiation
|
1.) Treat "y" as a function of x
2.) Differentiate both sides of the equation, with respect to "x" and use the chain rule where appropriate. 3.) Solve algebraically for y' |
