Generalized Stokes Equation I love this because it neatly summarizes things you learn in introductory calculus such as FTC, classical Stokes theorem, divergence theorem. It's also really aesthetically beautiful- the latin d signifying the exterior derivative turns into the greek ∂ signifying...

I believe 0 curl implies conservative if and only if your domain is simply connected. In your case the field has a singularity at 0. http://en.wikipedia.org/wiki/Conservative_vector_field

Well to find the derivative of f(x) you find the the slope of the tangent line at every point x. To do this imagine a secant line intersecting the function at 2 points, (x,f(x)), and (x+h, f(x+h)). Finding the slope of the secant line, which is [f(x+h) - f(x)]/h, will approximately give you how...
