Hello,
I try to solve this equation [math]\frac{dX}{ds} = -\frac{X}{R}[/math] I separate variables and calculate two separate integrals like this [math]\frac{dX}{X} = -\frac{ds}{R} \rightarrow ln(X) + C_1 = -\frac{s}{R} + C_2 \rightarrow X = e^{-\frac{s}{R}} + e^{C_2} - e^{C_1}[/math]
But this is not the right answer. What do I do wrong here?
