<p>I’m having my 2nd midterm for calculus 3 multivariable calculus on friday!! And I’m scared cause I don’t know anything…anyone want to help? The things I have most trouble on are:
integration over elementary regions (without fixed limits of integration)
how to tell gradient fields and curl fields
difference between vector fields/scalar fields/how to compute
<p>Partial implicit differentiation sucks, it killed me last test. If you have any specific questions, maybe I could help, but I don’t really know what you’re looking for.</p>
<p>Ok yea…partial differentiation is not making any sense…like if I have 4 variablees x,y,u,v, how am I supposed to solve for du/dx? or dv/dx? There are frickin 4 variables!!</p>
