Yea, you don't need to write full solutions, just the important steps will do.
hahahah lovin' the editsFixed latex, that is the right idea anyway, if you didn't make any mistakes its right
EDIT: Second integral is wrong
EDIT2: First integral is wrong as well
I was going to say an easy way to do this was using the AM-GM inequality, then I saw part (iii) lol.Yea, you don't need to write full solutions, just the important steps will do.
You'll have to prove the AM-GM inequality, it's not hard though:^ can the AM-GM inequality be stated in 4U to show/prove things like (x+y+z) >= 3 x cube root of x
i am very sorryUhhhh, there's no 3D trig in 2U? :/
Did you try part (i) yet?How come there are never any questions that are around the difficulty of the average 2U student? As much as I wish I could answer these, I just can't.
You don't need to use that identityYeah all I got to was changing to .

For part (i) of Sy's trig question, think about multiplying everything on the LHS by something.Thanks! Another question that's not too hard?
