Course Description:
This course provides a study of functions, equations, and formulas related to angles and triangles. Their
applications in mathematics, engineering and sciences are emphasized.
Final (20% of final grade)
The final is mandatory in order to receive a passing grade. More will be said prior to the final.
Homework
(5% of final grade)
Homework will be assigned weekly but will be collected at end of each chapter. They will be graded on effort and
returned. Homework related questions will answered during the first thirty minutes of each class meeting. Homework
will be assigned from odd number problems where the answers are available in the back of the text. You will find all
homework assignments as follows: http://creatingbytes.com/math240/hwassignments.html
Tests (75% of final grade)
A total of six in-class tests will be taken, excluding the final. If for any reason you are unable to take a test, I need to
be notified by email prior to the test date; otherwise a zero will be assigned. By notifying me, I will make a reasonable
effort to arrange for a make-up date or some other special mutually agreed arrangement.
If you are found to be cheating on a test, you will be asked to forfeit the examination, assigned a test grade of zero
and reported to the Dean of Students. Always keep your eyes on your own papers. Ref: Board Rule 9803.28
All tests will be closed book, but you will be allowed to have one 8.5 x 11 “formula” sheet containing only formulas,
unless otherwise specified, and a calculator. A violation of this rule will carry a consequence of relinquishing your
“formula” sheet. All tests will be taken in-class and limited to one hour. Test questions will be mainly problem solving
style problems. You will be required to show all work to receive full credit.
