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.
