help please how would you solve this
\[\ln(x-2)-\frac{ 1 }{ 2 }\ln(x-1)=-\frac{ 1 }{ 2 }\ln(y+1)+\frac{ 1 }{ 2 }\ln(y-1)\]
@sillybilly123
i already did the partial fraction already and thats what i got on both sides....
\(\ln(x-2)-\frac{ 1 }{ 2 }\ln(x-1) = \ln(x-2)-\ln(x-1)^{\frac{1}{2}} = \ln \dfrac{x-2}{(x-1)^{\frac{1}{2}}}\)
the other one?
\(-\frac{ 1 }{ 2 }\ln(y+1)+\frac{ 1 }{ 2 }\ln(y-1)\) \(= -\frac{ 1 }{ 2 } \ln( \dfrac{y+1}{y-1})\)
really sorry Marcie, I may not be concentrating as well as I should on this.
oh no D: .. its due tomorrow morning e.e
ok
i cant seem to get the answer... since the answer is
they want you to find the value of c
okay. so how do i do ...
hmm okayy so how do i do that bc i followed ur steps but i ended up with a different answer D:
this is a different thread, you present some algebra from some other thread, and then suggest that I have mislead you on something?!?! you're not for real ?
im just llost how they got that answer
Marcie, I am about to be suspended for nothing. I will, pending suspension, try to help.
wait whaa D:
no no im not saying that u mislead me... i followed ur steps.. its just that i got lost till the end of the eq
it's fine. :)
no no im not saying that u mislead me... i followed ur steps.. its just that i got lost till the end of the equation..
ah, i remember typing that out
this is what you posted from the previous post... i just got to the partial fraction. im trying to figure out how they got to the answer. im very bad at logs
OK!!
logs are actually very important
well yeh... thats where im stucked but im not getting to the answer...
\(\log A + \log B = \log AB\)
mmk
so then
this was number 9 and this is what i did
OK too tired tocheck anything but if YOU say that \(c = \ln C\) then you can add it into the logs on both sides and undo the Log thing. Make sense?
uhh
lets say that: \(\ln Y = \ln X + C\) And that: \(C = \ln C'\) So: \(\ln Y = \ln X + \ln C'\) Or: \(\ln Y = \ln C' X \)
what i mean is get that constant INSIDE the log
if is some constant so is log (C') but, in the latter form, you can stuff it inside a log function
\[\frac{ 1 }{ 2 }(-\ln(y+1)+\ln(y-1))\] \[\frac{1}{2} [ \ln(y-1)-\ln(y+1)] = \frac{1}{2} [\ln(\frac{y-1}{y+1})]\]
hmm ok
as he said on the other post it will be easier to multiply both sides by 2 to get rid of the fraction
yeah, "he" said that
he/she*
the trick is getting a constant C inside another constant log(C) so you can use log rules
Sorry i jumped ino the middle of this please carry on
no you didn't.
Can you please carry on?
still there ??
71 vs 69 there's only 1 winner there
🤔
good job..
TU, ma'am :)
