Answer :


Given :


To show :


Formula used : =


=



If u and v are functions of x,then = u + v


The CHAIN RULE states that the derivative of f(g(x)) is f’(g(x)).g’(x)


y = x +


y2 = xy + 1


Differentiating with respect to x


= + 0 (as differentiation of constant is zero )


2y. = x. + y


= y


=


=
