if theta = 45degree , then find the value of 2cosec square theta + 3sec square theta

Answer :

Given  :  θ = 45°

To find value of 2 Cosec 2 θ + 3 Sec 2 θ , We substitute θ = 45° and get

2 Cosec 245° + 3 Sec 2 45°2  22 + 3  22                     (  We know Cosec  45° = Sec  45° = 2 )2 × 2  + 3 × 2  4  +6  10                                            ( Ans )
