The Attempt at a Solution
This is part of a larger question, I have underlined in Red the areas I am struggling with and have cut out bits I have done.
Any ideas?
I have done some research and found out about 'Gibbs Phenonemon', http://www.sosmath.com/fourier/fourier3/gibbs.html
can't really get it all together to answer the question.
any help is appreciated, thanks! :)
