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

1)Find the inverse of a f(x)=1+e^x/1-e^x

2)solve for x when e^ax=ce^bx where a doesn't equal b.

2. Relevant equations

1)ln(e^x)=x

2)ln(e^x)=x

3. The attempt at a solution

1)

(1+e^x/1-e^x)(1+e^x/1+e^x)=(2+e^x^2/2)

ln(2+e^x^2/2)= ln2+x^2/ln2

sqrt(ln2/ln2)=x

I think this is what x comes out to but I'm not sure.

2)

ln(e^ax)=ln(ce^bx)

ax=bxC

a-b=x-x

Again I'm not sure if this is right, any help is much appreciated.
