Text: Elementary Technical Mathematics, 11th edition, Ewen and Nelson, Brooks/Cole Cengage Learning Note: The calculator may be used on graded work in this course once the student has demonstrated to the instructor's satisfaction, an understanding of the concepts that can be duplicated by a calculator. The instructor may require that the student have access to a scientific calculator in this course. Calculators may be used for tests and the final. Test problems should be designed to insure that the student has learned the fundamental concepts and does not depend on the calculator for thinking as well as computing. The student should show all equations and required backup work for a problem. Attention should be given to the correct use of significant digits and appropriate rounding of approximate numbers (measured quantities.) Lab work should include hands-on applications and provide additional drill material on the given topics, as well as individual help to students. It should be a time of supervised, guided student work. (Samples on file in bottom drawer of file cabinet located in PH379. There are also some books you may borrow and sign out.) Note: The instructor should applications in each chapter. emphasize problem solving and Note: The order of the topics was chosen with the Technical Trades Departments. Instructor may prefer to do 12.1 and 12.3 (Pythagorean Theorem) before chapter 13.

Thoughts to share for MA106 In the bottom drawer of the file cabinet in PH379 is an expandable folder with material that may be copied for MA106. There are also books that may be checked out. Please feel free to share any of your comments, ideas, or labs with others teaching the course now or in the future. Most folders contain both a lab and extra problems which are in the same folder separated by a colored piece of paper. Please leave at least one copy in the folder, thank you. Lab on Angles: Before doing the lab, students should be able to 1) draw and measure angles, 2) work with parallel lines and transversals, and 3) use the Pythagorean Theorem. Circle Lab: See first page of lab for equipment needed, etc. Surface Area/Volume Lab: (Redoing to measure objects - the 3 dimensional models as well as objects in their field of work located in AB 208) Plotting Points: (For now plots a cartoon character but would like to redo one that plots a technical diagram.) y = mx and y = mx + b: These might be used as the introduction to these sections as class discussion with students. By using graphics calculators, they explore and discover the effects of m and b, etc. Application of lines: Students will write equations of lines from information gathered from using protractors to measure acute, obtuse and reflex angles. Solving Pairs of Linear Equations: This lab uses the CBL units and the graphics calculators. If you need help or have questions, contact Gabriel Melendez or Nelissa Rutishauser. y = a sin x and y = a cos x: These might be used as the introduction to Chapter 14 as class discussion with students. (You might go over page 1 of the lab together with the graphics calculator overhead screen and then the student can complete the other pages). By using graphics calculators, they explore and discover the effects of a. Graphing Trigonometric Functions by plotting points: This might be used to introduce 14.1, calculating and plotting points, and then followed by frequency and period examples from the text. y = a sin bx and y = a cos bx: Colored pencils are helpful (and may be found in AB208 cabinet or file drawers). Law of Sines: This lab takes two hours and covers all of the cases of the law of sines through construction. Hence, protractors are needed again. Law of Cosines: This may take one hour.
