The value of (sin 30°+ cos 30°) - (sin 60°+ cos 60°) is

1.	The value of (sin 30°+ cos 30°) - (sin 60°+ cos 60°) is
Answer» Sin 30° - 1/2 Cos 30° - √3/2Sin 60° - √3/2 Cos60° - 1/2(1/2 + √3/2) - (√3/2 + 1/2)(√3 +1)/2 - (√ 3+1)/2 = 0 (sin30+cos30) - (sin60+cos60)\xa0sin30 = 1/2\xa0sin60= √3/2\xa0cos30= √3/2\xa0cos60= 1/2\xa0=> (1/2+√3/2) - (√3/2+1/2)\xa0=> 1+√3/2 - √3+1/2\xa0=> 1+1+√3-√3 /2\xa0=> 2/2\xa0=>1
