tan²60° + 4 cos²45° + cosec²60° + 2cos²90°

__________________________________     =   2.1

2cosec30° + 3sec60° - 7/3 cot²30°

Step-by-step explanation:

For the given problem,

The values are

tan60°      = √3

cos45°      = 1/√2

cosec60°  = 2/√3

cos90°      = 0

cosec30°  = 2

sec60°      = 2

cot30°       = √3

By subtituting these values in the question,

                    tan²60° + 4 cos²45° + cosec²60° + 2cos²90°

              ______________________________________

                     2cosec30° + 3sec60° - 7/3 cot²30°

                   (√3)² + 4(1/√2)² + (2/√3)² + 2(0)

        =       __________________________

                          2(2) + 3(2) - 7/3( √3)²

 

                       3 + (4/2) + (4/3)

          =         ______________

                           (4 + 6) - 7

                          3 + 2 + 1.3

             =         __________

                              10 - 7

             =   6.3/3

             =   2.1

Therefore, the simplified answer for the given question is 2.1
