therez total 7, C L = 2! rest 5=5!

therefore = 2 x 5!
nahh because when you group the C and L together you end up with 6 groups
i.e. O, Y, M, P, I, CL
and that^ can be arranged 6! ways but the C and L can be arranged within each other 2 ways so its D, 2 x 6!

No, I said IF it was C then it would be 6pi and be restricted to 3pi, but its restricted to 3pi/2 so it ends up being D
wtf bro?
u say -pi/2 < y/3 < pi /2 and u get -3pi/2<y<3pi/2 (and that's the fkin graph)

Re: General Thoughts: Mathematics Ext 1

Listen the thing with 5 is that it says the C and L can be in ANY ORDER....there is no need to multiply by 2. You just treat the C and L as one letter and go 6!

It's the fact they say they can be in any order that means you DO multiply by 2.

If they had to be in a specific order they could only be together in 1 way, which would mean just 6!.

"C and L in any order" means order is not defined, so you need to account for "CL" and "LC" as separate

5 is D.
I can't be C.
you need take C and L as one.
Therefore, they can be arranged 6!, then C and L can be arranged 2 ways.
It is D.
