WitrynaA short cut for implicit differentiation is using the partial derivative (∂/∂x). When you use the partial derivative, you treat all the variables, except the one you are … WitrynaAn implicit function is a function, written in terms of both dependent and independent variables, like y-3x 2 +2x+5 = 0. Whereas an explicit function is a function which is represented in terms of an independent variable. For example, y = 3x+1 is explicit where y is a dependent variable and is dependent on the independent variable x.
