This unit aims to increase confidence and ability in mathematical skills, to provide an introduction to the understanding of mathematical principles of algebra and trigonometry and to introduce systematic problem solving techniques. It includes a review of basic algebra; involving introduction to algebraic functions and their graphs; trigonometric functions, properties and identities; elementary theory of vectors; elementary matrices and linear algebra.

At the completion of this unit students will be able to:

  1. apply elementary manipulative skills to solve mathematical problems
  2. formulate simple applied problems in mathematical language
  3. use the principles of elementary trigonometry, vectors, and linear algebra, in the solution of problems.
