anonymous one year ago Is this right?

yes, but the only change I would make is to write 0.1666 as 1/60 instead

3. Vocaloid

*0.01666

4. DanJS

watch your notation, the summation of 1/3 is 1/3

5. anonymous

are we looking at the same question ??

6. anonymous

I posted #3

$\sum_{i=1}^{4}$ is the total of those 4 partial sums

9. anonymous

so I calculated all of them, then summed them in the end

10. DanJS

Yes, your first calculation says $\sum \frac{ 1 }{ 3 }$ which is 1/3, the summation of 1/3

11. DanJS

you did it correct, just the notation is slightly off

12. anonymous

Oh okay okay. Thank you !

13. DanJS

The first one is maybe, for i=1 $f(x _{1},~y _{1}) = 1/3$

14. DanJS

not 1/3 sorry, the -10.67 you got

15. DanJS

and you are finding the summation for i=1 to i=4 $\sum_{i=1}^{4}f(x _{i}~,y _{i})$

goodluck
