You forgot the + C

Ah yes

Thanks

Remembering your log rules log(3x+3) = log(3) + log(x + 1) which is valid when you account for the constant + C

log xy = log x + log y is valid in the domain of log

#

$$\ln |x+1| - \ln|3x+3| $$ is a constant, there is no contradiction

calculate definite integral in (a,b) where a >0, say

you get the exact same result

pastel turtle Why both give differents results #p

because there is an infinity of primitives

#

btw u did a mistake

#

u should add the constant C at the end

#

because the constant C which determines primitive u search

#

for example ,if we take C = 0 for the first integral and C = -(ln3)/3 for the second integral , we will have the same primitive of the integral

#

for that the constant C is verry important and u should add it, as i sad because there's an infinity of primitives.
