calculus - Is there a g such that intlimitsaafracf(x)g(x)mathrmdx=intlimitsa0f(x)mathrmdx for *odd* function f?

It was shown that if f is continuous and even on [a,a],a>0, then aaf(x)1+exdx=a0f(x)dx.



I wonder are there any similar property holds if f is odd? So my question is as follow:



If f is continuous and odd on [a,a],a>0, is there a function g such that aaf(x)g(x)dx=a0f(x)dx?
