That's peculiar. You are looking for "final answers", not just "answers"?

In any case, those look like pretty standard Calculus problems that you should, if this is to be a final exam, have already learned. The first asks you to do a path integral over |x|+ |y|= 1. Do you know what that path is? It consists of four straight lines, each pretty easy to "parameterize". Have you done that?

The second asks you to do a triple integral, with respect to x, y, and z, of \(\displaystyle (x^2+ y^2+ z^2)^2\). Have you multiplied that out? It is \(\displaystyle x^4+ y^4+ z^4+ 2xy+ 2xz+ 2yz\). What is the integral of that with respect to z?

The third asks you to find the "curl" of a given vector function. Do you know how the "curl" is defined?

Well first thanks for reply.Why does it peculiar ? I cant reach to teacher and i cant find the answers thats why looking for someone to help :)
i dont care about the answers i am just looking for final answers. I know it can be peculiar for you but this is how i solve problems i dont care about the path i care about the result.
I failed on this lesson and i am taking again. I cant go to classes cos i dont have time for it (taking another lessons at same time )
1)https://scontent-ams3-1.xx.fbcdn.ne...=bd77b50ebdbcd2a0464e2888dccf1343&oe=587C1195
I solved for first region and multiplied final result with 2 (in order to my final note i failed on this :) )
2)z5/5 + x*z^2+y*z^2 then ?
3) no i dont have any idea ill work for it.

What's peculiar is your making a difference between "final answers", which you say you want, and "answers", which you seem to suggest that you do not want. What is the distinction, in your mind?

Or are you saying that you don't care about the steps; you only want the final hand-in values?

That makes zero sense. If you don't understand the steps, there is no way to go about getting the answers to similar exercises. If you've never even seen the steps, it is quite unlikely that you'd divine them on your own.

Perhaps the "final answer" is that you should avoid enrolling in courses for which you have no time and from which you have no desire to learn anything. Either way, we won't be completing your test for you. Sorry. :roll:
