1. The problem statement, all variables and given/known data i have to integrate e^(-y) / y and i found out that you have to use this exponential integral and someone else said it doesnt have an integral. either way im thoroughly confused 3. The attempt at a solution i have no clue what so ever. The original question had it in dy/dx=y*e^(x+y) but that above question is all i need help with.
