Do Now Which of the following statements could be true if ? A) B) C) D) Only A and C could be true (but not simultaneously…)
Implicit Differentiation Section 3.7b
We can use Imp. Diff. with other familiar processes, including finding tangents, normals, and/or higher- order derivatives… Find the second derivative: (when )
To find the second derivative, simply differentiate again: …and substitute for y’ so that we have y’’ in terms of x and y: (when )
