R3
(a) Write fR. 2x dA as an iterated integral, both in the "dx dy" order and in the "dy dx"
order. Then, evaluate one of the two integrals.
(0,-2).
(b) Set up fr 2x dA as an iterated integral, both in the "dx dy" order and in the
"dy dx" order.
(c) Use polar coordinates to evaluate fa (x²
+ y?) dA.
(d) Use polar coordinates to evaluate fp 12x dA, where R is the region formed by combining the regions R1
and R2.
(e) Set up, but do not evaluate, an iterated integral equivalent to fs 2x dA, where S is the region formed by
combining the regions R2 ad R3. Use whatever coordinate system you think is easiest.
