2021 Spring – MAT 2680 – Differential Equations – Reitz

2021 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. Avatar and site header created using https://hipsterlogogenerator.com/

2020 Spring – MAT 1375 Precalculus – Reitz

2020 Spring – MAT 1375 Precalculus – Reitz

This course is designed to prepare students for the study of Calculus. Topics include an in-depth study of functions such as polynomial functions, inverse functions, radical functions, rational functions, trigonometric functions, exponential and logarithmic functions; solving inequalities; elements of vectors and complex numbers; solving trigonometric equations and identities involving sum, double and half-angle formulas; Binomial Theorem; and progressions. A graphing calculator is required. Avatar designed at logomakr.com.

2020 Fall – MAT 2571 – Introduction to Proofs – Reitz

2020 Fall – MAT 2571 – Introduction to Proofs – Reitz

Preparation for teaching an advanced mathematics curriculum with a focus on the processes of mathematical argumentation and reasoning, deduction, and discovery. Topics include propositional and firstorder logic, axiomatic approach to number theory, set theory and abstract properties of relations, with a particular emphasis on number theory.

MAT 2680 Model Course

MAT 2680 Model Course

This model course is designed for use by faculty teaching MAT 2680 on the OpenLab – it includes a number of resources and sample assignments to help you get started. If you are a faculty member, you can “clone the course” to create a copy for your use, and customize it in whatever way you wish. For help with cloning and customizing, take a look at the online module Getting started on the OpenLab with Math Model Courses.

My Projects

Math Department Curriculum Committee

Math Department Curriculum Committee

This site is a place for Math Department Curriculum Committee members to make announcements and share resources and ideas.

Undergraduate Research

Undergraduate Research

Realizing the value of the research experience at the undergraduate level, this project is committed to fostering research opportunities for City Tech students. Faculty and students can use this project as a place to share announcements about research opportunities, as well as a place to offer information about the experiences students and faculty have had in their research endeavors. A handbook on effective mentoring, developed by the Undergraduate Research Committee, is currently available for download.

Opening Gateways Project Management

Opening Gateways Project Management

This is a private group for members of the management team of “Opening Gateways to Completion: Open Digital Pedagogies for Student Success in STEM,” a Title V Cooperative Arrangement grant funded through U.S. Department of Education’s Supporting Hispanic-Serving Institutions program. The project, a collaboration between City Tech and the Borough of Manhattan Community College, is focussed on using Open Digital Pedagogies to increase student success in gateway mathematics courses for STEM disciplines.

Open Pedagogy on the OpenLab

Open Pedagogy on the OpenLab

The purpose of this project is to create a forum to ask questions, generate discussion, and share teaching materials, resources, and ideas about teaching and learning on the OpenLab. Avatar image: “The open door” by hehaden.

Comforting Content for COVID Coping

Comforting Content for COVID Coping

The OpenLab Community Team would like to invite the City Tech community to join this project as a space to share comforting content– baby animals, rainbows, photos of your pets, nature scenes, soothing music or videos, wholesome memes, etc. All members will be added as “Contributors,” meaning you can create your own posts featuring whatever comforting content you love, which will then be curated by the Community Team. If you’re interested in writing about your own experiences during the COVID-19 outbreak or reading submissions from others, this project is not intended for that purpose, but we’re hoping to launch a separate place on the OpenLab for our campus community to commiserate (alliteration is fun!) very soon.

My Clubs

Student Government Association

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

Math Club

Math Club

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.
