2024 Spring MAT 2680 Differential Equations Reitz
A differential equation is an equation that relates a function to one or more of its derivatives. – The above rather boring description does little to convey just how fundamental, widespread, and amazingly effective differential equations are in describing the world around us. – Examples: Anything in motion. Also, many things that are not in motion. Also, many additional things to which the word “motion” does not really apply. – Further examples: spaceships in orbit, populations growing and shrinking, a cup of coffee slowly cooling, springs bouncing, financial markets rising and falling, electrical current flowing through a circuit, ocean waves, sound waves, light waves, vibrations in musical instruments and airplane wings and suspension bridges, – More examples: Pretty much everything. Topics include methods of solving ordinary differential equations and applications to various problems. Site header created using nightcafe studio, avatar created using Adobe Express

2023 Fall – MEDU 3000 – Mathematics of the Secondary School Curriculum – Reitz
The course examines the content of the secondary school mathematics curriculum from an advanced perspective. Pedagogical content knowledge is examined in discussions of mathematical concept representations, student errors, and the design of activities.
MAT4880 Mathematical Modeling II, Spring 2019
The study of continuous-time and discrete-time nonlinear dynamic models. Provides examples of chaotic behavior of solutions of some dynamic systems.

My Projects
WeBWork on the OpenLab is a place where you can ask questions and discuss WeBWorK homework problems, and also see what other students have been asking. Visit the project site to see it in action!
The Open Road is our place to highlight all that’s possible on the OpenLab. Join now to keep up on OpenLab news, events, and updates. Check our weekly In the Spotlight posts for a glimpse into the incredible work being done by City Tech students, faculty, and staff. Follow OpenLab News for announcements and site updates. And see our OpenLab Calendar for office hours, events, and workshops. You can find our workshop schedule and signup for workshops here as well. The Open Road is also a place for the OpenLab community (meaning you!). We would love your feedback, insight, and comments. Please send along anything on the OpenLab that you love! We are always available for any questions you might have. Email us anytime at openlab@citytech.cuny.edu!
This is a collaborative space for student interns working on the OpenLab Team.

Mathematics Department Adjunct Faculty
A central resource where the Mathematics Department can communicate internally with adjunct faculty, with meetings, deadlines, announcements and more.
My Clubs
Student Government Association
The Student Government Association is the representative body for students. We are responsible for recommending student activity fee allocations, shaping policies affecting student life, coordinating extracurricular events and chartering new organizations. Feel free to contact SGA President, Lucas Almonte, with any questions, suggestions or concerns. He can be reached at SGAPresident@CityTech.Cuny.Edu If you wish to start a club on campus contact SGA Vice President, Sylwester Dombroski, at SGAVP@CityTech.Cuny.Edu
What do mathematicians do? Can mathematics be fun and interesting? Do you like free pizza? The Math Club is open to everyone with an interest in logic puzzles, games of chance or strategy, and mathematics in general. We host a variety of math related events, math talks, math games, math puzzles, field trips, math competitions, and more. Feel free to stop by on Thursdays in Namm N719, from 1-2pm.
