Let's face it: there will almost certainly be questions, or parts of questions, in your exam papers that you just can't do. Maybe you've forgotten the method, or the algebra is too hard, or you don't understand what is being asked, or you simply get stuck. OK, so you probably won't get 100%. But there are also lots of very common slips which lead to unnecessary marks being lost; do your very best not to fall into these numeric and ...

An exponential function is any function where x is raised to a power, for example $f(x) = 1.5 \times {2^{x}} + 10$. For most of this blog I will concentrate on $2^x$, but the same rules apply whatever the base of the power is. 2x is not the same as x2 They feel like the same sort of thing, don't they, but they're completely different functions. Look at the graphs: yes, both functions increase rapidly for x > 0, but they're very different to the left of the y-axis ...

So, here are ...

Just in case you're not willing or able to take on the whole of Sarah Blakewell's At the Existentialist Cafe, (New York, 2016) I thought I'd provide you easy access to some points from her summary on page on page 34.  Sometimes it's good to just have a solid reference point to play your ideas against, particularly if you are reading works by Sartre or Camus.  These, remember, are her 'take' on some important facets that she sees in the ...
