证明题.
教我如何积分足矣

it's not hard.
i will tell you the steps.
first split the denominator into (3c+s)(3c-s)
then integrate with partial fractions.
then everything becomes easy to handle.
get it?the key is PARTIAL FRACTION
the result i get is
1/6{log[3cosx+sinx]-log[3cosx-sinx]}
and you simply plug it in.
good luck with your problem set.
