f{x, y, z)dV Evaluate the triple integral Q f(x, y, z) = 2xz + xy Q is the tetrahedron bounded by x + y + 2z = 2 and the coordinate planes. 2/3 2 4/15 1/5Solution
f(x,y,z)= 2xz+ xy
x+y +2z= 2
y=0 and z=0 ==> x=2
0<x<2
z=0 ==> y= 2-x
0<y<2-x
2z= 2- x-y ==> z= (2- x-y)/2
0<z< (2- x-y)/2
\\int_{x=0}^{2} \\int_{y=0}^{2-x} \\int_{z=0}^{(2-x-y)/2} (2*x*z+x*y) dz dy dx
= 4/15 ANSWER
