### NCERT Sol Maths Class XII Ch-6 | Application of Derivatives

Solution of Important Question of NCERT Book Class XII Chapter 6 Matrices Get Free NCERT Solutions for Class 12 Maths Chapter 6 Application of Derivative.  Solution of important questions  of NCERT book  solved by Expert Teachers as per NCERT (CBSE) Book guidelines.   Exercise 6. 3 Q 18    For the curve    y = 4x 3  – 2x 5 , find all the points at which the tangent passes through the origin. 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 =
