Unit 2
Vectors and Oblique Triangles
Unit Objective
Understand vectors and be able to combine them graphically and by adding their components. Find the components of a vector and be able to solve oblique triangles using the law of sines and cosines. This unit should take no more than 2 weeks to complete.
*All assignments are in Basic Technical Mathematics With Calculus 7th edition by Allyn J. Washington, 2000.
Method of Evaluation
The unit test will be a pencil and paper exam given 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.
