MHB Possible title: Troubleshooting File Attachments on Online Forums

[jameszy7]

a) The two surfaces defined by xz^2 + 2yz +xy^2 = 4, 2x - 7y - 3z = 2 intersect in a curve S. Find the tangent line and normal plane to S at the point (3,1,-1).


b) Sketch the graphs of y = x^m and y = x^n where m and n are positive integers and x >= 0 . Find the area of the region enclosed between them. Is your answer valid for m>n or m <n ?

c) Let F = e^x i + 2ye^x j + e^2y^^2 k

(i,j and k are not part of the power)

Verify the divergence theorem over the box-like region described by
0<=x<=1, 0<=y<=2, 0<=z<=3.


d) Evaluate the triple integral

\int_{2}^{0} \int_{2x}^{0} \int_{y}^{0} xe^z dzdydx
Sorry if this looks messy, its my first post here :D

Hello jameszy7 and welcome to MHB! :D

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?

Hi, Whenever I try to post something, it never works when I attach a document. I am not sure the reason to that.

Hi, Whenever I try to post something, it never works when I attach a document. I am not sure the reason to that.

What is the extension of the file, and the size of the file. We support certain file extensions and have a maximum size an attachment can be, which can be based on the file's extension.

What steps are you using to attempt to attach the file? What happens when you try to upload the file and/or submit your post? What kind of error message(s) do you receive?
