Page1/1            I started with Euler's identity and manipulated it 2011-11-14 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.     Solve e^x + e^(x+1) = 250 2008-08-25 From Laura:"solve this equation correct to three decimals" e^x + e^x+1= 250Answered by Penny Nom.     The inverse of a function 2008-05-03 From keith:please help me find the inverse of this function: h(t) = 2 + 4 ln(1-5t)Answered by Stephen La Rocque.     Two derivatives 1999-11-16 From Gina Renicker:The derivative of: y=e(xlnx) and y=x2arctan(x1/2) Answered by Harley Weston.     Slopes of curved lines 1999-06-09 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.     Natural Logarithm Functions 1997-04-23 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.Answered by Harley Weston.
