(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

e^x - e^-x all divided by 2 = -1

express answer in natural logs

2. Relevant equations

No equations, just properties of logs and natural logs

3. 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 thats right because it says express answer in natural logs so it should simplify out that easily.
