we have then
in the same fashion you can take the second one.
Hello,
In my complex variable class my teacher went over the inverse function theroem and got into some advanced calculus concerning the Jacobian. He said it can be used in real variables to produce all forms of the chain rule through matrix multiplication.
I wanted to try it out with some real valued functions from my calculus book. However, I guess I didn't really understand something, or missed some conditions, because I am trying to use the jacobian to answer the following calc3 questions.
1) If has continuous second order derivatives and and , find (those d's should be currled).
2) , where and , find .
My work so far has been a dead end. I can find them using the chain rule, but now with the jacobian, because I am not sure how to construct two jacobian matrices from the given information. For instance,
in the first one, has only two partial derivatives, one with respect to x and the other with respect to y. I can find a 2 by 2 jacobian for x and y because I can find partials with respect to r and s for both.
Any help would be great. I dont really need answers, but help with the method would be great
Thank you
