An implicit function of x and y is a function in which one of the variables is not directly expressed in terms of the other. In other words, you use implicit differentiation when both x and y are on the same side. To implicitly differentiate an implicit function follow the steps below.
1. Apply all differentiation rules. Except to y.
y3 - x2 = -5
y3 - 2x = 0
2. Then differentiate the y's in regard to x. In turn you add a y prime to the differentiated y's.
3y2y' -2x = 0
3. Now factor out any y primes. Hint. In this example there are none.
4. Lastly, place all the y primes on one side.
y' = (2x) / (3y2)
