Question

Is it right to say sin-60°cos 30° + sin 30° cos 60° = sin(60°+30°).​

Answer 1

Answer:

No

Step-by-step explanation:

sin-60°cos 30° + sin 30° cos 60° = sin(60°+30°).

- sin60°cos 30° + sin 30° cos 60° = sin(60°+30°).

sin(30°-60°)=sin(60°+30°).

- sin30° does not equal to sin(60°+30°).

i hope your confusion is clear now
