TEXT: Technical Mathematics, Ewen, Gary, and Trefzger Edition 2. Older Editions are OK
CALCULATOR: A TI 83, 84, or 89 or equivalent is required
Course Description: This is an overview of basic mathematical applications for electronic and
electrical circuit analysis, IT, HVAC, construction engineering drafting, and technical physics.
The course includes fundamental concepts of operations with real numbers, measurement and the
metric system, fundamental algebraic concepts and systems of linear equations, graphing,
exponential and logarithmic functions, right angle and oblique triangles, basic trig functions,
vectors and complex numbers. The main focus of the course is developing processes to analyze
technical applications, and developing critical thinking skills to predict or determine outcomes
from real industry situations.

Homework is due on Thursday, following the week that it is assigned.
Each homework assignment will be graded out of a possible 10 points. 2 points will be
deducted for each day that you homework is late without prior approval from the
instructor (stuff happens).
If you are having difficulty, talk to me about tutoring right away!
Always work in teams on your homework.
Please submit your homework in the following format:
