Simple solution to a very difficult-looking problem!
For this I would name two graphs as 1 and 2. So, G r a p h 1 : x = y n G r a p h 2 : y = x n Area under g r a p h 1 will be the area under y − a x i s , A r e a = ∫ 0 1 y n d y A r e a = n + 1 1 Similarly area under g r a p h 2 will be area under x − a x i s , A r e a = ∫ 0 1 x n d x A r e a = n + 1 1 By adding up areas we get, A r e a = ( n + 1 ) 2 1 0 0 9 1 = ( n + 1 ) 2 n = 2 0 1 7 I didn't knew this problem was linked with new year BTW Happy New Year 2017!
