Dear aspirant,
First of all you need to analyse what can be done in this question whether you should go for substitution , partial fractions or sometime even both. So you put sin x = t and then after diffrentiating it you will get cosx dx = dt then your integral becomes dt/(1-t)(2-t) then apply partial fraction.
