Implicit Differentiation and the Second Derivative
ocw.mit.edu › courses › mathematicsAs with the direct method, we calculate the second derivative by differentiating twice. With implicit differentiation this leaves us with a formula for y that involves y and y , and simplifying is a serious consideration. Recall 2that to take the derivative of 4y with respect to x we first take the derivative with respect to y and then multiply by y ; this is the “derivative of
