Can someone explain why the probability of the inclination angle of a binary system being less than i_0 is 1-cos(i_0)(adsbygoogle = window.adsbygoogle || []).push({});

i.e. why the fractional distribution of binary stars is df = sini * di, where i is the inclination angle?

Where does the sin i come from? Why is not not uniformly distributed across angles?

Thanks.
