Question 4iii) here https://www0.maths.ox.ac.uk/system/files/coursematerial/2015/2637/9/sheet3.pdf

Honestly i have no idea where to even begin (apart from just subbing the numbers in and verifying those values are correct). I have scoured the library but can't find anything even remotely similar. Any hints would be appreciated

I have not quite seen a question like this.
I will look at it tomorrow

I have been stuck on this for about a day and a half...

I will try to steal it ...
One bad thing about being logged to TSR is that "my to do list" is getting longer

nvm i figured it out
