the natural logarithmic function uses exponent integer e as its base value whose constant value is 2.718.

natural logarithmic functions are easily converted into its relative exponential functions as following:

log e y = x

to convert it into exponential form both RHS and LHS are put in exponent’s power as

e log e y = ex

we know that the exponents and logarithm are opposite to each other so

e cancels the log on LHS:

y = ex

‘e’ is also known as Euler Constant.

Okay so here is my problem. For work, I have a curve that I need to put into
excel and find the graphing equation. So I look at the curve and record data points
from the curve into excel. I will then graph the points and it will produce a
curve just like the one have on paper. My problem comes when I ask excel to
produce equations for the curves. The equations it produces do not match the
curves when I enter a value into the equation. Why does this happen or how
can I fix it?

1/1+a^n + 1/1+a^-n

My attempt:
=1/1+a^n + 1+a^n/1
=1+{1+a^n(1+a^n)}/1+a^n
=1+1+2a^n+a^n^2/1+a^n
=2+2a^n+a^n^2/1+a^n
let a^n=m
=2+2m+2m^2/1+m
=2(1+m+m^2)/1+m

I don’t know what to do next, the answer is supposed to be 1.

will you please simplify the expression its very urgent i tried on many sites but didn’t get the correct answer according to my mathematics textbook.
