Question

(sin30 +cos30) -(sin60+cos60)​

Answer 1

Answer:

(sin30+cos30)-(sin60+cos60)

(1/2+√3/2)-(√3/2+1/2)

1+√3/2-(√3+1/2)

1+√3-√3+1/2

1+0+1/2

2/2

1

Answer 2

$(sin30 +cos30) - (sin60 + cos60)$

We know that,

sin30 = 1/2

cos30 =   √3/2

sin60 =  √3/2

cos60 = 1/2

So, put these values in the given question :-

(sin30 + cos30) - (sin60 + cos60)

(1/2 +  √3/2) - ( √3/2 + 1/2)

(1+ √3)/2  -  (1+ √3)/2

(1 +  √3 - 1 -  √3)/2

0/2

= 0
