This is the second volume of the textbook "Fundamentals of Advanced Math-ematics" written by the same authors. It includes vector algebra and analytic geometry in space, multivariable calculus, and linear ordinary differential e-quations. The intentions and features are as introduced in the preface to the first volume. We repeat here the important advice to students in the first vol-ume, as it is equally important for this second volume.
In order to learn calculus, it is not enough to read the
