Answer 1

Answer:

-0.44

Step-by-step explanation:

1/2+1/2-root3/2+root3/2

=2/4-root6/4

=2-root6/4

=-0.44

Answer 2

Answer:

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

= [sin 30° + cos ( 90°- 30°)] - [sin 60° + cos ( 90° - 60° ) ]

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

= ( 1/2 + 1/2) - ( √3/2+ √3/2)

= ( 1+1/ 2 ) - (√3 +√3/ 2)

= 1 - 2√3/2

= 1 - √3
