If ω = 2π/T then 1/T ∫ from 0 to T of 1/2*m*ω^2*A^2*cos^2 ωt dt=? A)1/2 m*ω^2*A^2 B) zero C) 1/4 mω^2 A^2 D) 1 I got B) zero as the answer. Is it correct?

Is it correct? i am pretty sure B) is wrong. running it through in my head (not sure how confident you want to be in that ) i got C) do you get zero when you do ? nope. so the answer can't be zero

What is ? I dunno...
