Implicit Differentiation and the Second Derivative

Implicit Diﬀerentiation and the Second Derivative Calculate y using implicit diﬀerentiation; simplify as much as possible. x 2 + 4y 2 = 1 Solution As with the direct method, we calculate the second derivative by diﬀerentiating twice. With implicit diﬀerentiation this leaves us with a formula for y that
