About Derivative of Function in Parametric Form

Sometimes the relation between two variables is neither explicit nor implicit, but some link of a third variable with each of the first two variables, separately, establishes a relation between the first two variables. In such a situation, we say that the relation between them is expressed parametrically. The third variable is called the parameter. More precisely, a relation expressed between two variables x and y in the following form x = f (t), y = g(t) is said to be parametric form with ‘t’ as a parameter. In order to find differentiation of functions in such form, we have by chain rule.
