Because my solutions say so and the long-way calculation I did (which turns out to have a mistake in it now I check again) agreed with those instead of this!! Thanks. I was flabbergasted at how this could possibly be incorrect... what a relief.
Now you've got me curious! What was the "solution sheet" answer that "the long way" agreed with?
It only gave the first two terms but the solutions claim the co-efficient of the second term is 1/4 rather than 1/2
