1 Answer Sorted by 4 If f x f x is odd then f x f x x R f x f x x R a a f x dx 0 af x dx a 0 f x dx a a f x d x a 0 f x d x 0 a f x d x The rules for integrating even and odd functions If the function is even or odd and the interval is a a we can apply these rules When f x is even int a a f x dx 2 int a 0f x dx When

Or f x dx lim a b b af x dx Since f is odd the first way gives 0 this is what is called Cauchy Principal Value However the proper way to compute the improper integral is the second way The reason why is because we want in some sense to take the supremum over all intervals a b R Now let s dig into integrals of even and odd functions Let f be an integrable function on some closed interval that is symmetric about zero for example a a for a 0 If f is even then a a f x d x 2 0 a f x d x If f is odd then a a f x d x 0
