Question

The value
of cosec²57°- tan²33° - tan²
45° is​

Answer 1

Answer:

I dont now sorry

Answer 2

Answer:

1/sin^2(57°) - sin^2(33°)/cos^2(33°) - tan^2(45°)

1/sin^2(57°) - cos^2(57°)/sin^2(57°) - tan^2(45°)

1 - cos^2(57°)/sin^2(57°) - tan^2(45°)

sin^2(57°)/sin^2(57°) - tan^2(45°)

1 - 1^2 =
