So you are in for some fun with real analysis, at the moment I f****en hate the subject and want a professor that actually teaches you how to solve Taylor series problems or even explain what it is!

Yeah I got that value by calculator.

As for question 10 I used induction but wasn't happy with my proof, but hey meh.

This guy is not teaching us the fundementals and I hate it!

Yea it's a bit weird how he doesn't teach us the actual concepts...., I mean he just does random questions from the problem sheet, his website 'notes' are just a mess as-well lol..

I've read a bit of (Baby) Rudin and Spivak to help elucidate the concepts, and that's helped a little bit, but I hate self-learning mathematics from textbooks.

The other thing I find really bizarre is the length of this assignment - almost 80 questions long!, when the first assignment from last year only had 8 questions...

Surely you covered taylor series and series in general last year?

No it wasn't covered!

Pappa-Bohr can you back me up that we really haven't covered Taylor series.

your lecturer is an idiot if you haven't covered taylor series amd he/she expects you to do these questions...

Ok I was looking through the lecture outline and apparently we go into more detail further down the track.

We've covered examples of the questions, so we can most them, but we haven't actually covered the theory or purpose behind them.
I mean it's like we're still waiting for the proper theory lectures to start, and up and till now we've been doing warm up questions or something..

It's a very oddly structured subject.

but hey we have a different lecturer for the next few weeks so maybe it will get better.

So have you been able to do q70?

He hasn't shown us how to find the sum of a series.

Yeah but how can we get that without a calculator?

i dont know.
 post it and see if anyone else can do it?

also did you do the q 60 in the Taylor series section?

I did question 60 and I'll give you a hint:

Find the series expansion of ex in powers of 'x+3'.

As for question 70, I'm going to just leave it.

Did you do calculus last year? Taylor series aka power series aka power expansion (etc etc) is one of the first things they teach you in single-variable calculus at uni, along with convergence and divergence of series, it was even covered in enhancement.

This question is really bugging me!

Evaluate:



Graphing it on my graphics calculator shows it approaches e if you don't exceed 1010, but it approaches 1 if you go past 1014.

WTF!!!!
