HallsofIvy Posted November 2, 2020 Share Posted November 2, 2020 It's interesting that this test on "Electro-magnetic theory" is pretty much a Calculus test! Link to comment Share on other sites More sharing options...
joigus Posted November 2, 2020 Share Posted November 2, 2020 At what point are you stuck? Can you parametrize a curve? Can you calculate components of curl or calculate div? Do you even know what they are? Link to comment Share on other sites More sharing options...
SAADU ABDULLAHI Posted November 2, 2020 Author Share Posted November 2, 2020 Actually I don't know... Link to comment Share on other sites More sharing options...
joigus Posted November 3, 2020 Share Posted November 3, 2020 Can you do ordinary polynomial integrals and derivatives? Give me something. What is it you don't know? Link to comment Share on other sites More sharing options...
HallsofIvy Posted November 7, 2020 Share Posted November 7, 2020 (edited) Are you sure you are taking this course? Perhaps you accidently went into the wrong class and were given homework for a course you aren't taking! The first problem asks you to integrate [math]\oint_L x^2y da_x- y da_y[/math] around the path consisting of the straight line from (0, 0) to (1, 1), then the straight line from (1, 1) to (2, 0), then the straight line from (2, 0) back to (0, 0). The first line can be written as y= x so dy= dx and [tex]dl= \sqrt{(dx)^2+ (dy)^2}= \sqrt{(dx)^2+ (dx)^2}= \sqrt{2}dx[/tex] with x from 0 to 1.
