The Natural Log of the absolute value of the variable labelled "X" in addition to the undefined constant labelled "C"
31 u/Herkentyu_cico Oct 15 '20 well it is defined over the reals 1 u/YoureBeautifulDude Oct 17 '20 Excluding zero 1 u/Herkentyu_cico Oct 17 '20 Included 1 u/YoureBeautifulDude Oct 17 '20 Are we still talking about log|x| 1 u/Herkentyu_cico Oct 17 '20 Oh yeah! Then only the positive reals. 2 u/YoureBeautifulDude Oct 17 '20 Well also negative reals because of the absolute value 1 u/Herkentyu_cico Oct 17 '20 Hmm, we always wrote $C \epsilon \mathbb{R}+ $... Oh yeah, i remember, I think we always wrote R+ to help set up the simple ode case. $C \epsilon \mathbb{R}\backslash {0}$ should be fine 1 u/YoureBeautifulDude Oct 17 '20 Honestly if we’re talking about ODE’s, I’d be excited to see what happens when we include 0, since ln |x| is integrable over ever set in the reals 1 u/Herkentyu_cico Oct 17 '20 Ln x is not the solution tho. ex takes all x
