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
What is the mode of this data set? (41,43,3,11,23,24,27,29,45,12,19,22,25)

Answer:
no mode
Step-by-step explanation:
there is no mode in this data set
this is because there is no number that repeats itself making no number have more quantities than another number
