Write in dark blue or black pen. You may use an HB pencil for any diagrams or graphs. Do not use staples, paper clips, glue or correction fluid. Answer all the questions. Write your answers in the spaces provided in the question paper. Give non-exact numerical answers correct to 3 significant figures, or 1 decimal place in the case of angles in degrees, unless a different level of accuracy is specified in the question. You are expected to use an approved graphing calculator. Unsupported answers from a graphing calculator are allowed unless a question specifically states otherwise. Where unsupported answers from a graphing calculator are not allowed in a question, you are required to present the mathematical steps using mathematical notations and not calculator commands.

2 Section A: Pure Mathematics [40 marks] 1 The position vectors of points A, B and P with respect to an origin O are a, b and p respectively, where 3 2.= −pab (a) Show that A, B and P are collinear and hence find the ratio :.BP AP [4] (b) It is given that b is a unit vector, 4 3=a and the angle between a and b is π .3 The point N is a point on li ne BP which is closest to the origin . Find the value of BN BA . [5] 2 (a) Logarithmic functions are useful as measurement units for phenomena with large scale of values, such as decibels (for sound) or Richter scale (for earthquakes). Logarithmic functions make the measurement units smaller and easier to work with. An example of a logarithmic function is given as ( ) 2ln 1 2 3 .y xx= ++ (i) By using differentiation, find the Maclaurin series for y , up to and including the term in 2.x [4] (ii) By using the standard series in MF26, verify that the answer obtained in part (i) is correct. [2] (b) Find the series expansion of , 4 x x+
