Solution Set 1 posted

I have posted the solutions to the first exercise sheet.

Note: Thomas Woolley (the TA) has mention that when asked to show things with delta functions that many people used the 'definition' of it being infinite at one point and 0 elsewhere. The whole point of doing distributions is that that is not good enough, so consider yourself warned that doing something like that for exam solutions is not going to result in a lot of points. As we have discussed in lectures, the definition of things like delta functions is based on distributions, and I will expect your answers to reflect that.
