Answer 2

given

2 sin square 30° - 2 cos square 45° + tan square 60°

we know that

{sin30°=(1/2)

cos45°=(1/√2)

tan60°=(√3)}

substitute these values

2×((1/2)^2) - 2×((1/√2)^2) +(√3)^2

2×(1/4) - 2×(1/2) + (3)

(1/2) -1 + 3

5/2

answer is 5/2

2 sin square 30° - 2 cos square 45° + tan square 60°=5/2
