    I was told by my lecturer to approach Taylor series from the left and from the right....

    What the hell? - I failed to ask any more questions before we went away for 2 weeks. I'm supposed to meet up with him when he comes back to show him what I've found out but what he gave me is very little to go on.....

    Does anyone have a clue what this leads to or is about?

    Thanks in advance!

    Who the hell is your lecturer? I'm thinking he was just too lazy to give you some proper work.

    Closest approximation -
    from the left - find out why Taylor series 'work' and why they are alternate representations of functions
    from the right - find out the (extremely numerous) applications for taylor series.

    I think it's something different...

    I think he's after something like, you see the Taylor series on wikipdia: http://en.wikipedia.org/wiki/Taylor_series

    He scribbled down on the back of my log book in pencil "a a+L = x".

    He didn't say much at all and that's all he's written down....

    I know what the taylor series is and it's applications etc.... but I'm still puzzled, is there something I haven't learnt some where?!

    Unfortunately, it's not a lecture, it's just mini-projects-type-things....

    I've been paired up with a weird person, our meetings last less than 5 minutes and he's so brief....

    Gah......

    I think he wants me to approach "a" from the left and from the right...

    I have NO idea why and what it's meant to lead to.... ?!!! :confused:

    Such a depressing module.....

    Maybe he's talking about, for example, the function f(x)=\frac{1}{1-x}. The Taylor series are different for -1 < x < 1 and x>1, (the former series is 1+x+x^2+x^3+..., which clearly diverges when x \geq 1). so he might want you to approach the point 1 from the left and right using two different Taylor series.

    Then again, I have no clue.
