Course Objectives and Expectations on Students:

This course is a 4 unit course designed for students who are majoring in life sciences, particularly in biology. It is also for students wishing to satisfy SDSU’s mathematics requirement for General Education.

Biological sciences are rapidly expanding with an increased need for more quantitative analysis of the data. Mathematics and computers are becoming more important to the life science work force. The main objective of this course is to provide student basic calculus skills to develop mathematical models for biological sciences, to help analyze data from life sciences, and to use mathematics software for solving life science problems. The students are expected to appreciate the usefulness of differentiatial and integral calculus and differential equations to relate the mathematics of life science problems in their real life.

Scope and Purpose of the Course:

This course is an engaging introduction to differential and integral calculus and differential equations for life sciences.  It will introduce students to the basic concepts and methods of differential and integral calculus and applications to life sciences. The central themes of the course will be functions as mathematical models for life science problems, and determination and analysis of these functions by using differentiation and integration tools and computer software. For example, logarithmic and exponential functions can be used to model population growth; the temperature of a female human body has a diurnal cycle with the maximum and minimum temperature of a day found from a polynomial or trigonometric function; the build-up of toxicity in the bodies of growing children exposed to lead can be modeled by a differential equation, which is solved using integration. Quantitative description and analysis of these life science examples by using calculus will be taught in the course.

The course is intended to help students develop basic calculus thinking and problem-solving strategies that can be applied to life science problems.  By emphasizing mathematical methods of applications, this course will engage students in logical thinking, problem solving, and basic skills of data analysis and modeling in life sciences.

We will normally cover six topics: linear models, least square method, limits, continuity, concept of derivative, methods and rules of differentiation, graphing functions, optimization problems, and usage of computer software. Although you will be challenged, the overriding theme of the course is to gain the basic calculus skills that are essential to today’s life science workforce and researchers.

This Course Addresses GE (General Education) Requirement

This is a GE course. It addresses the GE requirement from three perspectives: (1) construct mathematical models for life sciences, analyze biological data, and communicate mathematical arguments, (2) apply differential and integral calculus an ddifferential equation skills to real world problems, and (3) illustrate relevance of mathematical concepts across boundaries of various disciplines.
