Implicit Partial Differentiation. Sometimes a function of several variables cannot neatly be written with one of the variables isolated.Fortunately, the concept of implicit differentiation for derivatives of single variable functions can be passed down to partial differentiation of functions of several variables. differentiate sin3x cos2x.
