Q11 of 147 Page 181

If x and y are connected parametrically by the equations given in without eliminating the parameter, Find dy/dx.

If, show that

It is given that


Now,



Similarly,


Let us consider,



Taking Log on both sides, we get



Therefore,



……………………………..(1)


Now, Consider



Taking Log on both sides, we get



Therefore,



……………..(2)


So, from equation (1) and (2), we get



Therefore, L.H.S. = R.H.S.


Hence Proved
