This course is a credit-bearing Precalculus Mathematics.


MyMathLab for Reasoning with Functions II is part of a series of MyMathLab courses built to support the New Mathways Project developed by the Charles A. Dana Center. The New Mathways Project embodies the Dana Center’s vision for a systemic approach to improving student success and completion through implementation of processes, strategies, and structures built around three mathematics pathways. 


Reasoning with Functions II is designed for students who have completed Reasoning with Functions I and intend to take Calculus or STEM coursework that requires a thorough knowledge of functions and algebraic reasoning. Reasoning with Functions II builds students' geometric and trigonometric reasoning skills, providing opportunities to explore dynamic geometric situations as well as build and use mathematical models that incorporate trigonometric functions. The MyMathLab course designed to be used with Reasoning with Functions II provides:

  • Interactive content to help prepare students for active classroom time
  • In-Class Interactive Lessons to support students through an active classroom experience, accompanied by notebook PDFs
  •  Homework assignments designed to assess conceptual understanding of important skills and concepts
  •  Additional resources for instructors to help facilitate an interactive and engaging classroom


Built in MyMathLab

Content developed by the Charles A. Dana Center at The University of Texas at Austin will be delivered through MyMathLab. MyMathLab is an online homework, tutorial, and assessment program that engages students and improves results. Within its structured environment, students practice what they learn, test their understanding, and pursue a personalized study plan that helps them absorb course material and understand difficult concepts.
