why is it that though?

- anonymous

-1,0,1,2,3,4, are 6 items

- myininaya

i might be losing my brain lol or something but why does that tell us to do 2(6)

- anonymous

i think of it this way
sum of 2(i)^0 from i=-1 to 4
= 2(-1)^0+ 2(0)^0+2(1)^0+2(2)^0+2(3)^0+2(4)^0 = 12
if you know something about arithmetic series it should help

- myininaya

i know but that 0^0 is confusing me
because it is undefined

- anonymous

0^0 is indeterminate
this is tricky here

- myininaya

i have always thought of it just like you said but I never thought about the 0^0

- anonymous

i don't know if this helps

- myininaya

I do thank you though for trying to help me i will give you a medal

- anonymous

does that help?
We are taking the sum of the y values for f[n]=n.
at f[-1]+f[0]+...+f[4]
a way of visualizing functions might help

- myininaya

but we have f(n)=2
omg omg
ok so we f(-1)+f(0)+f(1)+...
=2+2+2+
omg you are my hero

- myininaya

i never thought of visualing it as a function

- anonymous

lol, good. Was just about to suggest the f(n) = 2 thing =)
Glad you hit upon it.

- myininaya

:)

- myininaya

cyter eveytime i notice you post something i'm gonna give you a medal

- myininaya

i just went back through some old posts and probably gave you like 6 medals lol

- myininaya

i know alot of math. I didn't think anyone could really impress me on this site or save me.

- anonymous

one was probably enough

- anonymous

but its ok

- myininaya

i mean i exaggerate when i say save lol

- anonymous

I did exaggerate too

- myininaya

i have a masters in math but there are small things i just accepted rules on

- myininaya

its nice to understand

- anonymous

This is the best thing I like about collaborative learning
You get to learn and really reach levels of understanding you couldn't reach

- myininaya

Polpak is pretty smart and impressive but no one has ever rescued me like you lol
