![if f(−x)=−f(x), ∫_(−a) ^(+a) f(x)=0 ⇒∫_(−1) ^(+1) (x/(cos^3 x))=0](https://www.tinkutara.com/question/Q77037.png)
$${if}\:{f}\left(−{x}\right)=−{f}\left({x}\right), \\ $$$$\int_{−{a}} ^{+{a}} {f}\left({x}\right)=\mathrm{0} \\ $$$$\Rightarrow\int_{−\mathrm{1}} ^{+\mathrm{1}} \frac{{x}}{\mathrm{cos}^{\mathrm{3}} \:{x}}=\mathrm{0} \\ $$
