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!!
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.how do i evaluate this without a calculator?
(sum from k=1 to k=5) of 1/k
exactly. Very good.how would i do 1+1/4+1/9+1/16
would it be (1)/(x^2) from 1 to 4?
