Transcribed Image Text:Differentiating the equation implicitly with respect to x, we will treat y as a function of x. When we take
dy
the derivative of y with respect to x, the Chain Rule will be required and produce a factor that we will
dx
then isolate. Here, we will also use the Product Rule on the left-hand side.
