i am curious what grade you got, and if you mentioned Dr autobreadticon as a reference?

Can anyone help with the answers for the questions circled please?

I'm stumped on both of those :/ what level of maths are these questions, I do year 12 methods at the moment... Hope these questions don't come up on the exam :P

Four unit (not sure what the VCE equivalent is) -- pretty much the highest level of maths in the NSW HSC. Come on... I know some of you have engineering degrees here... step up!

Hey Gok, this is an integration by parts problem, combined with a watered down version of proof by induction. I'm limited to a phone for internet atm so can't attach anything, but for part a) if n=0 then we just integrate arctan(x) using ibp. Part b is algebraically a bit trickery, but done in the same way. part c you will need to use the results from parts a and b to substitute in for In-2. The second question is also ibp, but try doing the n=0 and n=1 cases first.

GL-Sideswipe- this problem applies some principles you would see in specialist math, but for us in Vic, this is more a first yr unimath problem, you certainly won't see it in methods!

Specialist Maths covers some of that if I recall, it's been a while I graduated High school in 96.

True, and in my career as an engineer I think I've used integration of any sort maybe 5 times..

since the question appears to have been answered satisfactorily for the moment, I won't bother brushing the dust off my old textbooks.

Thanks Ultra Mackness!
