These are the second and third semesters of the mathematics core curriculum. They provide a foundation for the continued study of mathematics and for the subsequent study of physical sciences, social sciences, and engineering. Topics in single variable and multivariable calculus, and elementary ordinary differential equations are studied. MA104 covers the differential calculus, the integral calculus of a single variable, and differential equations. MA205 investigates parametric equations; series and sequences; and the study of multivariable calculus including 3-dimensional geometry and vectors, functions of two variables, partial derivatives, and multiple integrals. Computer software is used throughout both courses.
