The value of `sin 50^(0)-sin 70^0+sin 10^0` is equal to `adot\ 0` b. `1` c. `2` d. `1//2`

Explanation

`sin 50° – sin 70° + sin 10°`



`= sin(60° – 10°) – sin(60° + 10°) + sin 10°`



`= sin 60° cos 10° – cos 60° sin 10° – sin 60° + cos 10° – cos 60° sin 10° + sin 10°`



`= -2 cos 60° sin 10° + sin 10°`
