Question

2 sin 60 - cos 180° + 1 sin 270​

Answer 1

Solve :- 2sin 60° - cos 180° + 1 sin 270°

Answer :-

we know that,

• sin 60° = √3/2
• cos 180° = (-1)
• sin 270° = (-1)

so, putting all values we get,

→ 2sin 60° - cos 180° + 1sin 270°

→ 2 * (√3/2) - (-1) + 1 * (-1)

→ √3 + 1 - 1

→ √3 (Ans.)
