Answer:
LHS=cos^4(A/2)-sin^4(A/2)
={cos^2(A/2)}^2 -{sin^2(A/2)}^2
={cos^2(A/2) - sin^2(A/2)}{cos^2(A/2) +sin^2(A/2)}
=cosA×1
=cosA
Just plug in 2 for p. 3*2 - 2 = 6-2 = 4
Answer:
I can't help I don't get this answer at all
Profess to the team it isnt preposterous because it means absurd and that doesn't make sense it isn't absurd cause then it would be an not a and it isn't distinctive
