Haha at the last minute I wrote n=>0. Pretty broad generalisation haha

lmao but i asked my teacher, it was n>3 somthing

Fuck. Fuckfuckfuckfuckfuck. n has to be a multiple of 4. Goddammit. Because k = 3/4*n and k has to be integral. ARGH.

what did you guys get for f (ii)

 

[bubblyxblues]

what did you guys get for f (ii)

I said that the values must be divisible by 4.
i.e. 4, 8, 12, 16 ...
What did everyone else put ?

 

[Artemkin]

for f) ii) I got n=4/3k for k=0,1,2,3....
BUT, i'm guessing n has to be an integer, so it should have been n=4/3k for k=0,3,6,9....

f i) wanted an expression...?

 

[Nooblet94]

f i) wanted an expression...?

Oh, well I put that down and then simplified. It was -12C3 2^3.

 

[cartoonmaiz]

I said n=4,8,12... would that also be marked right?? I didn't specifically say that n was a multiple of 4...
