Unit Five
Unit Objective: *All assignments are in Basic Technical Mathematics With Calculus 7th edition by Allyn J. Washington, 2000. Method of Evaluation: Objective One Objective Two Objective Three Objective Four Objective Five Objective Six Objective Seven Worksheets [Course Outline] [Home Page]
Solve two linear equations in two unknowns; approximate the solution graphically; solve the system
algebraically by substitution or addition-subtraction (elimination); solve the system using
determinants, Cramer's Rule; solve three linear equations in three unknowns algebraically or with
determinants, Cramer's Rule; evaluate 2 x 2 and 3 x 3 determinants.
The unit test will be a pencil and paper quiz taken at your class site. The test will be
administered by the instructor or by a proctor. Please see the course schedule for the
exact time and date of the unit test.
