SUMMARY
The discussion centers on the confusion surrounding the integration of the functions f'(x)/f(x) and the implications of constants in logarithmic functions. Specifically, the integrals of the two equivalent fractions, 2x/x² and 6x/3x², yield ln(x²) and ln(3x²) respectively. The difference arises from the constant factor, where ln(3x²) can be expressed as ln(3) + ln(x²), highlighting the importance of the constant of integration (+C) in determining the final result. This illustrates that while the integrands are equivalent, their integrals differ by a constant term.
