calculate I =∫_0 ^(2π)   ((cost)/(3 +sin(2t)))dt and J =∫_0 ^(2π)   ((sint)/(3 +cos(2t)))dt .
$${calculate}\:{I}\:=\int_{\mathrm{0}} ^{\mathrm{2}\pi} \:\:\frac{{cost}}{\mathrm{3}\:+{sin}\left(\mathrm{2}{t}\right)}{dt}\:{and}\:{J}\:=\int_{\mathrm{0}} ^{\mathrm{2}\pi} \:\:\frac{{sint}}{\mathrm{3}\:+{cos}\left(\mathrm{2}{t}\right)}{dt}\:. \\ $$

both are zero because of full periods
$$\mathrm{both}\:\mathrm{are}\:\mathrm{zero}\:\mathrm{because}\:\mathrm{of}\:\mathrm{full}\:\mathrm{periods} \\ $$
