Please do part(ii).My answer is 5.61% but the paper's answer is 5.31%.
Please check for me thanks...
let $\displaystyle f(x) = e^x$
$\displaystyle g(x) = 4 - e^x$
$\displaystyle h(x) = 2(x - \ln{2}) + 2$
$\displaystyle A = \int_0^{\ln{2}} f(x) \, dx + \int_{\ln{2}}^{\ln{4}} g(x) \, dx$
$\displaystyle B = \int_0^{\ln{2}} f(x) - h(x) \, dx$
calculate $\displaystyle \frac{B}{A}$.
