**Description**:

**Course overview:**

This course includes the study of first order differential equations, higher order linear differential equations, Laplace transforms, boundary value and initial value problems, qualitative analysis of solutions, and applications of differential equations. Very detailed information is often available. After successful completion of this course, students will be able to develop key concepts in Special functions and demonstrate the usefulness of ordinary differential equations for modeling physical and other phenomena. Complementary mathematical approaches for their solution will be presented, including analytical methods, graphical analysis and numerical techniques. The basic content of the course includes (First order equations, Mathematical models, Linear equations of second order, The Laplace transform, Linear systems of arbitrary order and matrices, Nonlinear systems and phase plane analysis).

**Course objective:**

* The student will be able to:*

**Description**:

**Course overview:**

This course studies real sequences and infinite series without assumption of previous knowledge. The notions of upper and lower limits are introduced and used sparingly as a simplifying device; with their aid, the theory is given in almost complete form. The usual tests are given: in particular, the root test. With its aid, the treatment of power series is greatly simplified. Uniform convergence is presented with great care and applied to power series. Final sections point out the parallel with improper integrals; in particular, power series are shown to correspond to the Laplace transform. Also we opens with a review of determinants, and linear equations, and then develops matrix algebra, including Gaussian elimination, and n-dimensional geometry, with stress on linear mappin.gs. We discuss partial derivatives and develops them with the aid of vectors (gradient, for example) and matrices; partial derivatives are applied to geometry and to maximum-minimum problems. The course introduces divergence and curl and the basic identities; orthogonal coordinates are treated concisely. One of the chapters is on integration, reviews definite and indefinite integrals, using numerical methods to show how the latter can be constructed; multiple integrals are treated carefully, with emphasis on the rule for change of variables; Leibnitz's Rule for differentiating under the integral sign is proved. Improper integrals are also covered; the discussion of these is completed , where they are related to infinite series. The concept of line and surface integrals is introduced. Although the notions are first presented without vectors, it very soon becomes clear how natural the vector approach is for this subject. Line integrals are used to provide an exceptionally complete treatment of transformation of variables in a double integral. Many physical applications. including potential theory, are given.

**Course objective:**

The goals of the Advanced Calculus course are to give an introduction to the subject of Real Analysis, and to continue the rigorous development of the theorems of Calculus to the areas of derivatives, integrals, and series of functions. Students should gain a more in depth understanding of these areas of Calculus and should increase their proficiency in proving various results. I hope to convey the usefulness of series of functions, the importance of the uniform norm, and the limitations of the Riemann integral. A focus is on learning to prove mathematical statements rigorously.
