Calculate curl F at (1,1,1): Confirm Answer

[aaronfue]

Homework Statement

Calculate the curl F:

F(x,y,z) = cos(x)i + sin(y)j + e^xyk at point (1,1,1)

Homework Equations

The Attempt at a Solution

After calculating ∇×F, my answer was:

curl F = 2.72i + 2.72j + 0k

I'd appreciate a confirmation of my answer.

No answer is possible until you say at what point you are evaluating the curl. Come on.

Sorry. Point noted in question.

 

[Dick]

Sorry. Point noted in question.

Yeah, my over sight. But I'm getting [e,-e,0]. My sorry. Can you check that again?

Yeah, my answer should be [e,-e,0]. I forgot to put a negative on the second rather than a positive.

Answer should be:

curl F = 2.72i - 2.72j + 0k

or

curl F = ei - ej + 0k

or

Then I'll confirm that.
