ADD. MATHS BLOG: Brain Teaser 7: Line of Symmetry, Maxima (or, Minima) Of Quadratic Function in Terms Of a, b and c
http://addmathsf45.blogspot.com/2014/07/brain-teaser-7-line-of-symmetry-maxima.html
For SPM, IGCSE Cambridge / Edexcel Yrs 10 / 11 Students). Tuesday, 8 July 2014. Brain Teaser 7: Line of Symmetry, Maxima (or, Minima) Of Quadratic Function in Terms Of a, b and c. The Brain Teaser: For quadratic function y = ax. Bx c, show that ax. Bx c ≡ a(x – s). M, where x = s = - (b/2a) is its line of symmetry; m = c - ( b. 4a) is its maxima (or minima, if a 0). In other words, if you substitute x = s into y = ax. But what is the value of s in terms of a, b and c? Bx c ≡ a(x – s). Have fun with maths!

For SPM, IGCSE Cambridge / Edexcel Yrs 10 / 11 Students). Tuesday, 3 June 2014. Brain Teaser 6: Differentiate y = Ae 2x Be -x, where x ≥ 0,…. A curve has equation y = Ae. Where x ≥ 0. At the point where x = 0, y = 50 and dy/dx = -20. Show that A = 10 and find the value of B. (5). Using the values of A and B found in part (i), find the coordinates of the stationary point of the curve. (4). My additional question: Express the exact values of the coordinates of this stationary point as (C ln. C = 1/3: D=30].

For SPM, IGCSE Cambridge / Edexcel Yrs 10 / 11 Students). Thursday, 1 May 2014. Brain Teaser 4: Find the centre and the radius of the circle with the equation x2 y2 – 4x – 6y – 12 = 0 (or, x2 y2 = ax by c, generally). If you are given the centre of a circle as (a, b) and the radius as r (directly or indirectly), you can easily use Pythagoras Theorem to derive its equation as follows:. X – a). Y – b). If you are given equation of a circle not in the above format but in already simplified form, say. 2013 S...
