Need some help on multivariable calculus. Will pay $$ through stars.

Hi, midterms are coming around and theres some things I don't quite understand fully. They mainly consist of rotations and derivatives. All in all, it shouldn't take you more than 20 minutes to explain. I will send you the file containing the problems and we can either go over through AIM or ventrilo. I will pay $50 for the first 30 minutes and we can discuss from there if we go over. PM me and briefly tell me your credentials. YOU MUST BE FULLY FLUENT WITH MULTIVARIABLE CALCULUS.

Here is an example of the types of problems we will be going through:

Consider the expression 1/sqrt(3a^2-2x)

If you interpret this expression as the formula for a single variable x, sketch the domain of this function as a subset of R.


If you interpret this expression as the formula for a function of two variables, a and x, sketch the domain of this function as a subset of R^2.
