SUMMARY

The equation presented is f:\Re\rightarrow\Re, defined by e^x f(x) + e^x f'(x) = f(x). To solve for f(x), one approach is to isolate f'(x) on one side of the equation. The discussion highlights the challenge of dividing by f(x) without knowing if it is non-zero, which complicates the simplification process.

The Attempt at a Solution


i don't know if [tex]f(x)\neq 0[/tex] so i can't divide by [tex]f(x)[/tex] which would make things pretty simple.
