question about writing logs in math (1 Viewer)

[hup]

when we write something with a log, do we write like

1 - ln (x+a)

or

2 - ln lx+al

How could you not know this ???
Are you still in prelim lols? (This is HSC forum btw) ;o

The only time i've ever used absolute values for logarithms are whenever i'm applying calculus to them..

I'm not entirely sure when you have to use them though.

You use 2 in MX2 when you integrate.

You use 2 in MX2 when you integrate.

Definitely never got told that. I'm aware that you're supposed to have absolute values around, but no one has ever specifically said it to me at school.

my teacher said we should but it doesn't really matter.

use number two ...you can never be wrong

Use the absolute values. It's according to the standard integral table. You can't be marked wrong. It's mathematically correct.
