Class Time MTWR: 1030 - 1135 in Palenske 221.
Student Hours MWF: 1500 - 1600; TR: 1200 - 1300; or by appointment. Palenske 224. See Student Hours for more information.
Text Calculus - Early transcendentals with MyMathLab Access - 3rd Edition by Briggs, Cochran, & Gillett. In-class notes will also be essential.
Asking Questions If you have question during class or student hours, I will answer at that time. If you have questions outside of those times, you can email me. I promise to respond within 24 hours. DO NOT expect a response after 5pm on any given day as I may be busy with my family. However, I will do my best to be as fast as possible.

Project Information

Projects in Math 245 provide students with the opportunity to use the contemporary computational software package Mathematica to explore concepts introduced in class in greater detail. By completing these projects you will not only gain experience using this powerful software package to solve multidimensional problems in calculus and geometry, you will also acquire valuable experience in technical writing as you will not only be graded on the correctness of your results, but also on how they are communicated in written form.

Grading Note: Projects count for 15% of your final grade, with the highest scoring project worth twice as much as any other project. Guidelines for project writeups, including a detailed grading rubric, can be found here.

Quizzes

Grading Note: Exams count for 30% of your final grade. The highest exam score (whichever it is for you) will count twice in your final grade. For example, if you earn exam scores of 75%, 85%, and 80%, your exam average will be (0.75+2(0.85)+0.80)/4 = 81.25%. The straight average of these scores is 80% so this policy would benefit you by adding 1.25% to your three exam average.

Mathematica Notebooks

Below are a variety of functioning Mathematica notebooks corresponding to example problems worked out in the classroom and elsewhere.  The best way to use these worksheets is to first download the file to your local computer, and then open the file using your local Mathematica program. A nice online tutorial for using Mathematica is available here.   You can purchase or lease your own copy here.

Student Hours
1500 - 1600 MWF; 1200 - 1300 TR; or by appointment

Student hours is time and space that has been specifically allocated for me (Dr. Mason) to help you (the student) with questions, life, class, or just to talk. You are STRONGLY ENCOURAGED to hang out with me as often as you can. Research demonstrates that their is a solid correlation between good grades and being engaged with class. Student hours is one way to reinforce that connection.
