possible typo on 2020 Question 3 Morning sitting

(1/1)

Xuanru Pan:
When I calculate, I get uyy=-6x-12y rather than -6x+12y, which makes it not harmonic. Is it a typo or do I miscalculate?

RunboZhang:
I agree with you, I think the solution has some small typos.

Xiaoyi Du:
Me too, I also got that. And I think there is also typo on this question part (b)

maoxiaoy:
Yes, this is what I got too

Xuefeng Fan:
Yes I am totally agree with you
