Homework Statement
e^x - e^-x all divided by 2 = -1
express answer in natural logs
Homework Equations
No equations, just properties of logs and natural logs
The Attempt at a Solution
First, I multiplied everything by 2
e^x - e^-x = -2
then i took the natural log of both sides and brought down the exponent
(x)Ln(e) + (x)Ln(e) = -2
so you can simplify that i think to
2xLn(e) = -2
so x= -2/(2Lne)
which Lne is 1 so
x=-2/1
x=-2?
I don't think that's right because it says express answer in natural logs so it should simplify out that easily.
