f (x)

I_{1} = \int_{0}^{\infty} f (x) d x,

I_{2} = \int_{0}^{\infty} f (3 x - \frac{1}{2 x}) d x,

\frac{I_{1}}{I_{2}}

I_{1} & I_{2}

I_{1} = \int_{1}^{2} \frac{d x}{\sqrt{1 + x^{2}}}

I_{2} = \int_{1}^{2} \frac{d x}{x}

I_{1}

I_{2}

Now what should be the correct relation between $I_{1}$ , $I_{2}$ and $I_{3}$ .

I_{1} = \int_{0}^{\frac{π}{2}} f (sin 2 x) sin x d x

I_{2} = \int_{0}^{\frac{π}{2}} f (cos 2 x) cos x d x

\frac{I_{1}}{I_{2}}

If $I_{1} = \int_{0}^{\frac{π}{2}} x s i n x d x & I_{2} = \int_{0}^{\frac{π}{2}} x c o s x d x$ , then which of the following is true?
