If I_1 =∫_( 0) ^(3π)  f (cos^2 x)dx and  I_2 =∫_( 0) ^π  f (cos^2 x)dx  then
$$\mathrm{If}\:{I}_{\mathrm{1}} =\underset{\:\mathrm{0}} {\overset{\mathrm{3}\pi} {\int}}\:{f}\:\left(\mathrm{cos}^{\mathrm{2}} {x}\right){dx}\:\mathrm{and}\:\:{I}_{\mathrm{2}} =\underset{\:\mathrm{0}} {\overset{\pi} {\int}}\:{f}\:\left(\mathrm{cos}^{\mathrm{2}} {x}\right){dx} \\ $$$$\mathrm{then} \\ $$
