Differentiation of the Function Given Parametrically
Suppose that there is function y(х) given parametrically:
Suppose that functions j(t) and y(t) are differentiable in parameter t and j¢t¹0, there is also the inverse function t=t-1(x). Then the derivative of function can be obtained by the formula:
