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)

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? - Dec 16th 2008, 01:47 AMbadgerigarQuote:

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?
