The trapezium rule, with 2 intervals of equal width, is to be used to find an approximate value for fe"dx . i) Explain with the aid of a sketch, why the approximation will be greater than the exact value of the integral. ii) Calculate the approximate value and the exact value, giving each answer correct to 3 decimal places. ii1) Another approximation to 'e*dx is to be calculated by using two trapezium of unequal width. The first trapezium has width h and the second trapezium has width (1– k), so that the three ordinates are at x= 0, x=h and x=1. Show that the total area T of these two trapezium is given by 7 =(r! + h(1- e*1) + e* ). iv) Show that the value of h for which T is a minimum is given by h = In'
