Question

Find the value of sin 60 cos 45​

Answer 1

Answer:

sin 60 is (root 3)/2

cos 45 is 1/(root2)

Answer 2

Step-by-step explanation:

We know,

sin 60° = √3/2 , cos 45° = sin 45° = 1/√2 , cos 60° = 1/2

⇒ sin 60° cos 45° – cos 60° sin 45°

⇒ (√3/2 × 1/√2 - 1/2 × 1√2)

⇒

∴ The required answer is √3-2/2√2
