Question

sin square 30 into cos square 45 + 4 tan square 30 + half sin square 90 + 1 by 8 cos square 60 is equal to 2​

Answer 1

Answer:

sin 30° = 1/2 , hence sin square 30° = 1/4

cos 45° = 1/√2 ,hence cos square 45° = 1/2

tan 30° =. 1/√3 , hence tan square 30° = 1/3

sin 90° = 1, hence sin square 90° = 1

cos 60° = 1/2 , hence cos square 60 = 1/4

according to given equation -

1/4 × 1/2 + 4× 1/3 + 1/2 × 1 + 1/8 × 1/4 = 2

1/ 8 + 4/3 + 1/2 + 1/32 = 2

2 = 2
