Question
plzzzzzzz clearly explain partial differentiation and countour integration
Partial integration is done on a function of many variables
with respect to only one varible.
Suppose f(x,y,z) = x^2 + y^3 + x/z.
Writing the d's funny gives df/dx = 2x + 1/z, df/dy = 3y^2, and df/dz = -x/z^2.
I found contour integration here:
http://en.wikipedia.org/wiki/Methods_of_contour_integration
Three areas it is used are for complex integration, in the Cauchy integral formula, and
for applying the residue theorem.
There is a crash course in contour integration here:

Well over 2,000 of them have been in calculus.
Education/Credentials
I aquired well over 40 hours of upper division courses. This was well over the number that were required.
I graduated with honors in both my BS and MS degree from Oregon State University.
I was allowed to jump into a few junior level courses my sophomore year.
