ln or loge?

[zada]

Am i allowed to write ln instead of log_e on exams? I've gotten into the habit of writing ln (it's shorter!).

[chid]

Shouldn't make a i difference but just to be sure I would stick with loge it's only 2 extra figures!

Don't do it. It's just calculator notation, not formal maths notation. It's the same as not being allowed to write 10^3 or whatever.

yeh they dont allow answers like 3E-5, so i wouldnt risk it

Yeah, loge looks nicer anyways. Much easier to understand in my opinion.

Just a quick question regarding logs on calculators:

How do you change the base from 'e' to something else? In catalog there's 'logbase' but i'm not too sure how to use it. I use a TI-89 btw.

thanks

For 89's, diamond->7 gets you the log command. From there, just type log(3,2) for Otherwise for 84 people, just use change of base and have ln(3)/ln(2)

perfect! thanks alot

I disagree.

Writing ln(x) in place log_e is common practice.

Just go to the wikipedia article on Natural logarithm, it's plagued with ln's instead of log's

Not sure if examiners take it the same way though. Teachers definitely hate it.

[brendan]

Yes you are. No one really cares, at least in higher level mathematics.

[shinny]

Yes but this is VCE land where writing intercepts only as numbers counts as a loss of a mark. I personally wouldn't risk it because I know my teachers definitely hated it. The risks outweigh the benefits o_o

Opposite at my school.  All my teachers use it.

I think it's personal preference.

Exactly.

Well if it's personal preference, doesn't that imply theres a chance you could lose marks? Then why risk it? But whatever, do what you want. This really isn't worth arguing over -_-"

My teacher uses when is one of the terminals for an integral.
I use when I write integrals (less cramped).
