Students in the Physical Sciences and Engineering. Applied Math, Engineering and Physics (AMEP) majors.

**Background and Goals:**Math 321 covers

*vector algebra*,

*vector calculus*and an

*introduction to complex calculus*. Math 321 was redesigned to provide mathematical preparation for Electromagnetism (PHYS 322) as well as further courses in Mathematics, Physics and Engineering such as Transport phenomena, Fluid and Solid Mechanics (ME 561, EMA 622) , Aerodynamics (EMA 521), Flight dynamics (EMA 523), Advanced dynamics (EMA 542), astrodynamics (EMA 550), satellite dynamics (EMA 642), Computer graphics, plasma physics (PHYS 525), differential geometry (MATH 561), for example. The course emphasizes understanding of the geometrical concepts and covers vector (Gibbs) notation, index notation (including summation convention) and linear algebra notation.

**Prior course**: Math 320 (Diff eqs with linear algebra). Math 320, 321, 322 are a core sequence for mathematics, physics and engineering.

**Subsequent Courses:**Physics 322 (E&M), Math 322 (PDEs, Fourier Series, Special functions)

**Course Content:**
