Thanks Mark!! -----Original Message----- From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] On Behalf Of Mark Lane Sent: Wednesday, November 29, 2006 2:11 PM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: OT - Math Question I was a math major in a former life 10+ years. 1/2(e^x + e^-x) = 4 e^x + e^-x = 8 (e^x)^2 + 1 = 8e^x Let y = e^x such that x = ln(y). y^2 + 1 = 8y y^2 - 8y + 1 = 0 Use quadratic formula, which is x = (-b +- sqrt(b^2 - 4ac))/2a, to solve for y in previous equation. Then x = ln(y) -----Original Message----- From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] On Behalf Of Ron Leach Sent: Wednesday, November 29, 2006 9:24 AM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: OT - Math Question Only 13 years?!? Try 22 years ;-). I'm thinking that this might be a start... 1/2(e^x + e^-x) =4 ln (e^x + e^-x)^1/2 = ln 4 ln sqrt (e^x + e^-x) = ln 4 but now where to go... -----Original Message----- From: windows2000-bounce@xxxxxxxxxxxxx [mailto:windows2000-bounce@xxxxxxxxxxxxx] On Behalf Of Costanzo, Ray Sent: Wednesday, November 29, 2006 9:51 AM To: windows2000@xxxxxxxxxxxxx Subject: [windows2000] Re: OT - Math Question There is not a chance in hell I could ever do this. It's depressing. Take me back to high school and I think I could do it. Now, 13 years later, I don't have a clue where to begin. I briefly discussed it with my brother who said: <quote> I don't have time to look at it right now, but my first thought would be to use the natural log function to pull x out of the exponent. Example: e^x = 4 ln(e^x) = ln(4) x(ln(e)) = ln(4) x = ln(4) Your equation may not be so easy, because you'll have ln(e^x + e^-x), so you can't just move the x out of the exponent. </quote> Ray at work -----Original Message----- From: Ron Leach It's been a long while in doing the math problems, so please pardon the OT. I was wondering if anyone would be able to help with the following math problem (a little break from the normal stuff :-)) 1/2(e^x + e^-x) = 4, solve for x. Thanks! Ron PS Maybe Jim has a math list? ;-) ***************************** New Site from The Kenzig Group!
