7. Verify One of the following results. ( 2 ) 6 " 3 (x2 + y?) da dy = 35 -71 / 2 rsin 8 cos 0 3TT (b ) r sin2 0 cos2 0 dr d0 = Jo 5128. Evaluate One of each of the following integrals. (a) 1 xy ery dxdy (b) / JD xy dA, where D is the region bounded by the line y = x - 1 and the parabola 92 = 2x + 6.(7 ) So Sy ( x 2 +72 ) dady = 3 STEPS : YOOTOUCHR. Sy (x 2 + 7 7 ) Ax = 7254 - 7"+ 3 35 = 3 35 ( ) S"S," xy "cy dady = 2 ( ( STerfill) - JTerfi (2) Vierfi (3) -JT erfi(1) 4 2 STEPS ! 4
