sorry i have two more questions..
how do i evaluate this without a calculator?
(sum from k=1 to k=5) of 1/k
and what is sigma notation? it says to write 1+2+4+8+16+32 in sigma notation
sorry i'm so lost i hate missing class!!(Headbang)

Should it be 16 rather then 18?Quote:

Note: a sigma notation is a way to write out a long sumQuote:

Does that match the book answer?
yes thank you very much that makes sense
how would i do 1+1/4+1/9+1/16
would it be (1)/(x^2) from 1 to 4?
Find a common denominator and convert all of the fractions to it, then add up the numerators. I know it seems like you should know a better way by now, but I don't think there is one.Quote:

exactly. Very good.Quote:

thank you! im still confused on summations though.
f(x)= 1/(x+1) from [0,1] and n=2
how do i set up the summation for LRAM, RRAM, MRAM, and the trapezoidal method?
