# Riemann Integrable Function : Upper and Lower Sums

Please see attachment.

Q. Show directly that the function

is integrable on R = [0,1] x [0,1] and find

(Hint: Partition R into by squares and let N , limUp = limLp = integrable

Up = upper Riemann sum of f respect to partition  U(f,p) =

Lp = Lower Riemann sum of f respect to partition  L(f,p) =
