WebImplicit differentiation is a way of differentiating when you have a function in terms of both x and y. For example: x^2+y^2=16. This is the formula for a circle with a centre at (0,0) and a radius of 4. So using normal differentiation rules x^2 and 16 are differentiable if we are differentiating with respect to x.
