For all those who thinks that Ex 8.3 is tought. Actually it's not that tough! Just you need clarification of concepts and need to learn all the formulas clearly. You should watch the Introduction video of this chapter properly before solving sums.

[@SushmaKumari-ng2re]

Four tricks to solve : STEP 1- convert into sin and cos STEP 2- fractions STEP 3- identities STEP 4- rationalization Mam was following first step And you are also correct we can convert by the method you are telling but at the end we have to convert cot^2 theta into cos/sin Thanks
