Question

Sin square 45 - cos 53cosec37/tan15tan75

Answer 1

Answer:

Sin²45° = 1/2   -------A.

cos 53° x co sec 37° = cos 53° / sin 37° = 1          -------------B.

tan 15° x tan 75° = tan 15° / cot 75° = 1            ---------------C.

Putting A. , B. , and C. in the given relation we get;

1/2 - 1/1 = 1/2 - 1 = -1/2

So the answer is (-1/2).
