## Courses Taught

- This course covers basic algebraic and trigonometric skills, algebraic equations, and functions. Topics include: mathematical induction, complex numbers, and the binomial theorem.
Prerequisite: MAT 56 or MAT 56.5

Course Syllabus - This course is a combination of arithmetic and elementary algebra. It includes the arithmetic of integers, fractions, decimals, and percent. In addition, such topics as signed numbers, algebraic representation, operations with polynomials, factoring, the solution of simultaneous linear equations of two variables, and graphing are covered.
Students who passed MAT 12, MAT 14, MAT 41, MAT 51, MAT 56, MAT 160, MAT 161, MAT 56.5, MAT 150.5 cannot take MAT 161.5.

Course Syllabus - This course is the first algebra course offered at the College. It includes such topics as algebraic representation, signed numbers, operations with polynomials, factoring, the solution of linear equations, the coordinate system, the solution of simultaneous linear equations of two variables, and graphing. This course is designed to prepare students for the CUNY Freshman Skills Assessment Test required for transfer to the upper division of CUNY, as well as for more advanced math courses. If a student passes MAT 12, the student should not register for MAT 51, since MAT 12 combines MAT 8 and MAT 51.
Students who passed MAT 12, MAT 14, MAT 41, MAT 51, MAT 56, MAT 160, MAT 161, MAT 56.5, MAT 150.5 cannot take MAT 161.5.

Course Syllabus - This is an integrated course in analytic geometry and calculus, applied to functions of a single variable. It covers a study of rectangular coordinates in the plane, equations of conic sections, functions, limits, continuity, related rates, differentiation of algebraic and transcendental functions, Rolle's Theorem, the Mean Value Theorem, maxima and minima, and integration.
Prerequisite: MAT 206 or MAT 206.5

Professor Retamoso’s YOUTUBE channel

Professor Retamoso was selected by The BMCC Technology Learning Community, an** NSF-funded project, and the Tech Equity Project to participate in the AI Across the Curriculum (AIAC) Faculty Fellowship program for 2024-2025**. This project started in June 2024. So far, Professor Retamoso and professors from other fields have been working collaboratively on the ethical and responsible integration of AI into BMCC courses. As a Calculus instructor, Professor Retamoso will thoughtfully incorporate AI into one of his Calculus classes.

The pilot phase is set for Fall 2024, with full implementation scheduled for Spring 2025, as part of this project Professor Retamoso completed the AI Ethics (MDL-220) and earned a certificate given by IBM SkillsBuild.
