Chapter 07.02 Trapezoidal Rule for Integration-More Examples Civil Engineering Example 1 The concentration of benzene at a critical location is given by      758 . 5 6560 . 0 75 . 1 73 . 32 erfc e erfc c where  dz e x erfc x z 2 So in the above formula  dz e erfc z 6560 . 0 2 6560 . 0 Since 2 z e decays rapidly as z , we will approximate  6560 . 0 5 2 6560 . 0 dz e erfc z a) Use single segment Trapezoidal rule to find the value of   6560 . 0 erfc . b) Find the true error, t E , for part (a). c) Find the absolute relative true error for part (a). Solution a)    2 b f a f a b I , where 5 a 6560 . 0 b  2 z e z f  2 5 5 e f 11 10 3888 . 1  2 6560 . 0 6560 . 0 e f 65029 . 0  2 65029 . 0 10 3888 . 1 5 6560 . 0 11
