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!
