1. The problem statement, all variables and given/known data Solve the initial value problem (y+e^-y)y'=sinx subject to y(pi)=0 2. Relevant equations 3. The attempt at a solution I'm not quite sure what to do with this one. I've scanned through my book and could find no similar problems in what we've done so far. I tried to plug in dy/dx for y' and use separation of variables, but then I get stuck unable to solve for y after integrating. I cannot seem to find a way to set this one up to create an integrating factor either. If someone could nudge me in the right direction, I'd greatly appreciate it.
