Mathematics Question from JEE Main 2024 · 27 January, Shift 2

Let f(x)=0xg(t)log(1t1+t)dtf(x) = \int_0^x g(t) \log\left(\frac{1 - t}{1 + t}\right) \, dt, where gg is a continuous odd function. If π/2π/2(f(x)x2cos(x)1+ex)dx=(πα)2α\int_{-\pi/2}^{\pi/2} \left(\frac{f(x) x^2 \cos(x)}{1 + e^x}\right) \, dx = \left(\frac{\pi}{\alpha}\right)^2 - \alpha, then α\alpha is equal to:
