Logarithmic properties question
I was solving a differential equation and separated my variables oppositely to how the mark scheme did it. Anyway, while I was finding my general solution, I was here:
ln(1550/2V-450)=2t/15
And the mark scheme had:
ln(2V-450/1550)=2/15t
So this made me wonder..
lf ln(x/y) = p/r
Is ln(y/x) = r/p
?
ln(1550/2V-450)=2t/15
And the mark scheme had:
ln(2V-450/1550)=2/15t
So this made me wonder..
lf ln(x/y) = p/r
Is ln(y/x) = r/p
?

No.
Rewrite each of the ln's as the difference of two ln's and it should be clear how they relate.

Ah I see now. Thanks!
