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.
