above is cos(5x/6), which gives 2 solutions on the green line (so minimum value is p = 5/6, with square bracket bc we get 2 solns when p is this

this is when p = 7/6, we just barely get 2 solutions but u already got this part
so p gotta be inbetween

was there an answer to question 9 in the multis.

[6.0, 6.2) ->the area under the curve is non-zero, so it couldnt include 6.0

and

[6.2, 6.4) -> the area was 2*0.1 = 0.2 less that 0.2 so it can't be this

and the other two were for decreasing function but it was increasing?
I agree with this, I've just been having the discussion with my teacher. I think the correct answer should be (6.2, 6.4)
