When calculating surface integrals do you have to calculate double integrals for dxdy, dxdz and dydz and add up or what?
Defennder said:If you use any 2 of the three variables x,y,z then you have to set up the double integrals with respect to them.
coverband said:But this is sufficient? If you integrate say with respect to dxdy and have correct and appropriate limits then this is the question answered so to speak. You don't have to go on and do dxdz and dydz?
coverband said:I appreciate the attention but is the answer to do you just integrate with respect to dxdy in all cases yes !?
coverband said:Thanks no more exams. So say if you have surface z=x+y+1 then you integrate with respect to dxdy and that's it finished problem solved
If you have x=z-y-1 then you integrate with respect to dzdy and that's it finished
You don't do all three and add them up or anything !?
