This is the second semester of the mathematics core curriculum. This course and Calculus II, the third semester of the mathematics core curriculum, provide a foundation for the continued study of mathematics and for the subsequent study of the physical sciences, the social sciences, and engineering. Combined coverage includes single and multi-variable differential calculus, single and multi-variable integral calculus, and differential equations. Throughout both courses mathematical models motivate the study of topics such as optimization, accumulation, change in one and several variables, differential equations, motion in space, and other topics from the natural sciences, the social sciences, and the decision sciences. MA104 covers single and multi-variable differential calculus including 3-dimensional geometry and vectors.
