why is it that though?

-1,0,1,2,3,4, are 6 items
myininaya
  • myininaya
i might be losing my brain lol or something but why does that tell us to do 2(6)
anonymous
  • 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
  • myininaya
i know but that 0^0 is confusing me because it is undefined
anonymous
  • anonymous
0^0 is indeterminate this is tricky here
myininaya
  • myininaya
i have always thought of it just like you said but I never thought about the 0^0

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

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
  • 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
  • myininaya
i never thought of visualing it as a function
anonymous
  • anonymous
lol, good. Was just about to suggest the f(n) = 2 thing =) Glad you hit upon it.
