How fast is the depth of the seed changing when the seed is 14 inches deep? The basic idea about using implicit differentiation 1. dx dy dx Why can we treat y as a function of x in this way? IMPLICIT DIFFERENTIATION . Implicit differentiation will allow us to find the derivative in these cases.

Implicit differentiation is an alternate method for differentiating equations which can be solved explicitly for the function we want, and it is the only method for finding the derivative of a function which we cannot describe explicitly. And we learned in the last section on Implicit Differentiation that `d/(dx)y^2=2y(dy)/(dx)` We can write this as: `d/dx(y^2) = 2yy'` Putting it together, here is the first derivative of our implicit function: `xy' + y + 2yy' = 0` [I am using `y'` instead of `dy/dx`.
