Here you will learn what is implicit and explicit function with definition and examples. Let’s begin – Implicit and Explicit Function Definition : A function defined by an equation not solved for the dependent variable is called implicit function. e.g. the equations \(x^3 + y^3\) = 1 and \(x^y\) = \(y^x\), defines y as an

Here you will learn what is homogeneous function definition with example. Let’s begin – What is Homogeneous Function ? Definition : A function is said to be homogeneous with respect to any set of variables when each of its terms is of the same degree with respect to those of the variables. For example, \(5x^2

Here you will learn what is cube root function with definition, graph, domain and range. Let’s begin – Cube Root Function The function that associates a real number x to its cube root i.e. \(x^{1/3}\) is called the cube root function. Clearly, \(x^{1/3}\) is defined for all x \(\in\) R. So, we defined the cube
