The equation of a curve is \(y = 2 + \frac{3}{2x - 1}\).
(i) Obtain an expression for \(\frac{dy}{dx}\).
(ii) Explain why the curve has no stationary points.
At the point \(P\) on the curve, \(x = 2\).
(iii) Show that the normal to the curve at \(P\) passes through the origin.
(iv) A point moves along the curve in such a way that its \(x\)-coordinate is decreasing at a constant rate of 0.06 units per second. Find the rate of change of the \(y\)-coordinate as the point passes through \(P\).
