So i did it but how can i provide the result by this wayHint: Show that f(x) has to be differentiable. Then differentiate both sides of the equation.
Yes i mean this integralDo you mean
[tex]f(x) = x + \int_{1}^{x} f(t) dt[/tex]
???
I'm not sure. Maybe use this:So i did it but how can i provide the result by this way
