From anonymous: I started with Euler's identity and manipulated it
e^i*pi=-1
e^-i*pi=(-1)^-1
e^-i*pi=-1
e^-i*i*pi=(-1)^i
e^--pi=(-1)^i
e^pi=(-1)^i
type it in in a calculator and you get e^pi=23.1406926... and
(-1)^i=0.0432139183... What did I do wrong? Answered by Robert Dawson.
From Stephen Ehrler: When one plots the graphs of y=2x, y=3x, y=xx When each of these graphs pass through point (0,1) do they have the same slope? I know they are different lines but is it possable that they have the same slope at point (0,1). Answered by Harley Weston.
From Rickson: The following two questions are some of my son's homework that he is having trouble with......any advice or assistance would be appreciated.
(eX)5=1000.............the X and 5 are exponents
lnx + ln(x+3) = ln10
In each question the problem is to find x.
