Answer:
hence cos ( 2 A ) = cos 2 A − ( 1 − cos 2 A ) = 2 cos 2 A − 1
Step-by-step explanation:Well we know that for two angles A , B
it holds that cos ( A + B ) = cos A cos B − sin A ⋅ sin B hence for A = B you get cos ( 2 A ) = cos 2 A − sin 2 A But sin 2 A = 1 − cos 2 A
31,830,000 in scientific notation is 3.183×10 to the seventh.
5 1/2 - 3 5/6 = how much she needs
Make them into common denominator
11/2 = 33/6 - 23/6
33 - 23 = 10
10/6 = 1 2/3 yards
