Solution: Given equation of the curve is    y = 4x 3  – 2x 5 ………….(1) Let (h, k) be any point on this curve. Let tangent to the curve at    point    (h, k) passes through the origin (0, 0) Equation of the curve at point (h, k) becomes y = 4x 3  – 2x 5 ,    ⇒     k = 4h 3  – 2h 5    ………..(2) Differentiating eqn. (1)    w.r.t. x we get \[\frac{dy}{dx}=4\times 3x^{2}-2\times 5x^{4}=12x^{2}-10x^{4}\] \[\left (\frac{dy}{dx} \right )_{(h,\;k)}=12h^{2}-10h^{4}\] Equation of the tangent at (h, k) is given by y – k = (4h 3  – 2h 5 )( x – h ) This tangent passes through the origion (0, 0) 0 – k =
