Let I-x222B-x3B1-0dx1-x2212-cosxcos-x3B1-

If $0 < α < π / 2$ then the value of $\int_{0}^{α} \frac{d x}{1 - cos x cos α}$ is
$π / α$
$π / 2 cos α$
$π / 2 sin α$
$π / 2 α$

Let $I = \int_{0}^{α} \frac{d x}{1 - cos x cos α}$

If 0<α<π/2 then the value of ∫α0dx1−cosxcosα isπ/απ/2cosαπ/2sinαπ/2α

Let I=∫α0dx1−cosxcosα

If $0 < α < π / 2$ then the value of $\int_{0}^{α} \frac{d x}{1 - cos x cos α}$ is
$π / α$
$π / 2 cos α$
$π / 2 sin α$
$π / 2 α$

Let $I = \int_{0}^{α} \frac{d x}{1 - cos x cos α}$
