i've only watched the first couple episodes of the latest season for GG.
it's a good start.
but there isnt as great an impact as before.
cant wait to continue this wednesday when i finish!!
it's question 7 e) from last year's HSC paper.
this is the worked solution for that part.
it says to multiply each term by 2h/gt1t2
but i dont think it's right
because LHS wont equal RHS
someone please help me
thx =)

School Rank 08: 56
and i need advice on how to improve on my english mark!!
thank you!
a,b,c,d are positive real numbers, each strictly less than pie/2.
i) Show that cos a cos b< or = {cos 1/2 (a+b)}^2
ii) Hence show that cosa cosb cosc cosd < or = {cos 1/4 (a+b+c+d)}^4
i cant solve the second part.
thx!=D
