Sigma

If K = 1, 2 then it will be X(i,j,1,l,m,n) + X((i,j,2,l,m,n)
I'm confused what does K_l means? How do you input K_l to the equation?

 

[Dr.Peterson]

What do "dari" and "dan" mean? And what do K¹ and K² mean, with superscripts rather than subscripts?

But it appears that K_l means the set of students of a teacher named l.

We really need to see the definitions of all the sets (K, M, N); and the wording of the definition of K_l confuses me, as I would have thought K, not k, is a set. Did you copy the statement exactly as given to you?

I'm sorry. These are the full sets.


K¹= group of students of lower-grade years
K² = group of students of higher-grade years
