never ever forget the 'dx'. Please...

i dont like putting dx.

[superflya]

its not the dx's its the effing +c that i dont like.

[Whatlol]

its not the dx's its the effing +c that i dont like.

yea thats worse i forgot it everytime!

[Cthulhu]

its not the dx's its the effing +c that i dont like.

I always lost a mark or two by forgetting +c's

THIS.

Hmm, I'm confused, I read somewhere when they ask find 'an' antiderivative we don't need +C but in essentials Ex 12C Q2, the answers includes +C. So I'm actually quite worried about this wording thing. To confirm "find the RULE/THE antiderivative" we need +C?

[Blakhitman]

Yes.

[kenhung123]

What about in the case of finding 'an' antiderivative?

[TrueTears]

an means a class of functions, no need for +c

the is a specific function of that class, need for +c

But umm, I am a bit confused because Ex12C q2 includes +C in the case of 'an antiderivative'

I've always wondered though, what if you put some arbitrary number as a constant?

[m@tty]

It would be acceptable. Just some explanation may be required.

in the eyes of a mathematician thatd be fine, heck most mathematicians im sure probs wont even bother with +c if it was a trivial "integrate this" question, however some tightass vce examiner may think not.

If you want to be absolutely sure, check out Q 2.a. from exam 1 last year. VCAA left out the '+C'
