MATH 140* is an important building block in the education of any professional who uses quantitative analysis. This course introduces and develops the mathematical skills required for analyzing change and creating mathematical models that replicate real-life phenomena. The goals of our calculus courses include to develop the students' knowledge of calculus techniques and to use the calculus environment to develop critical thinking and problem solving skills. The concept of limit is central to calculus; MATH 140 begins with a study of this concept. Differential calculus topics include derivatives and their applications to rates of change, related rates, linearization, optimization, and graphing techniques. The Fundamental Theorem of Calculus, relating differential and integral calculus begins the study of Integral Calculus. Antidifferentiation and the technique of substitution is used in integration applications of finding areas of plane figures and volumes of solids of revolution. Trigonometric functions are included in every topic. 

CAS 100A explores how people use techniques of oral communication to address practical, professional and civic problems. It is designed to introduce students to principles of effective public speaking, implemented through the design and presentation of individual speeches. Drawing upon concepts from the study of both rhetoric and communication science, the course aims to foster habits of ethical self-reflection alongside practical speaking skills. 

*In order to be registered into MATH 140, students must either have (1) taken calculus in high school, or (2) score a 76 or higher on the ALEKS math assessment. If you select this pride and have not taken calculus in high school, you must complete your ALEKS math assessment by May 1, 2025. The ALEKS math assessment becomes available to students in their New Student Orientation Tasklist in March. For questions, contact us at leap@psu.edu. 

**MATH 140 is a 4-credit course. Students who select this pride will be registered in 7 credits. Tuition estimates on this website are based on enrollment in 6 credits. Students should plan for an additional approximately $850 (in-state resident) or $1,700 (out-of-state resident) in tuition cost for the additional credit.
