Hi, I am fairly new to line and curve integrals - I was wondering how to the following question:

Evaluate: The curve integral C of (x/((x^2)-(y^2)))dx + (y/((y^2)-(x^2)))dy

where C is any curve from (1,0) to (5,3) in the xy plane that does not meet the lines y=x and y=-x.

Also, could someone please let me know how to write proper mathematical symbols in this forum like I've seen in some of the threads.

Thanks.
