Evaluate the foll

Answer :

By trigonometric identities,


cot 45° = 1/tan 45° = 1/1 = 1


sec 30° = 1/cos 30° = 2/√3           [, cos 30° = √3/2]


cosec 60° = 1/sin 60° = 2/√3         [, sin 60° = √3/2]


sin 30° = 1/2


tan 45° = 1


cos 60° = 1/2


Putting all these values in , we get



Since, numerator is equal to denominator in the above calculation, we can say
