I hope that I'm going to make sense here. I found the Jacobian of two functions by taking the partial of F1 w.r.t x, then y and same for F2.

My professor did it by taking the partial of F1 w.r.t. y, then x, same for F2. So I have a 2x2 matrix. When i go to find the determinant, mine's negative and hers is positive. Isn't it supposed to be the same thing no matter which way you do it? this is driving me NUTS!

It looks like this

[-a -b]

[-c d]

so I get -ad-bc

hers is

[-b -a]

[d -c]

so she gets bc+ad

What is the deal? What does it mean?

2. Relevant equations

w.r.t means with respect to
