    Integrals-plz check out....

    1)double integral over[ (0 to a/sq.root 2),(y to sq.root of (a2-y2)] fn->log(x2+y2)dxdy &a>0

    2)int (0to pi/2) d(theta) int(0 to a sin theta) dr int(0 to (a2-r2)/a) r dz

    3)evaluate triple integral over V funtion=> z dx dy dz, where V is the solid tetrahedron bounded by the 4 planes..x=0,y=0,z=0&x+y+z=1

    9) evaluate teriple integral over V, fn=> xy dx dy dz, where V is the solid tetrahedron with vertices(0,0,0),(1,0,0),(0,2,0) and (0,0,3)
    10) evaluate triple integral over V fn>x dx dy dz, where V is the paraboloid x=4(y^2)+4(z^2) and the plane x=4....

    Can I please have the figures too???.....Kindly do it if u can

    Try to reply, today or tomorrow(as fast as possible).....am just in need.....

    Please try to give a general description on each type of question, so that i can do other such types of question easily by referring that...

    We're not an answering machine. Start with question 1, show us what you've done so far and where you get stuck, so we can nudge you into the right direction.
