In mathematics, differential calculus is a subfield of calculus that studies the rates at which quantities change. Suppose we have the equation F(x,y)=0. In this unit we explain how these can be differentiated using implicit differentiation. In this function, y is an implicit function, then we use. As we have seen, there is a close relationship between the derivatives of e x and ln. We suppose that an equation of the form F (x, y) = 0defines y implicitly as a differentiable function of x, that is, y = f (x), where F(x, f(x)) = 0 for all x in the domain of f.If F is differentiable, we can apply Case 1 of the Chain Rule Differentiation formulas; the power, product, reciprocal, and quotient rules; The chain rule; Differentiating trigonometric functions; Higher Order Derivatives; Implicit differentiation; Rates of change per unit time; related rates; Velocity and Acceleration; Differentials and Newton's method In implicit differentiation, all the variables are differentiated. without the use of the definition).
