MTT 108 - Mathematics for Occupational Technologies

Course Description

This course is designed to provide the student with relevant theory and skills in solving practical, industrially based mathematical problems. Topics of instruction will include, but will not be limited to, calculating arithmetic expressions involving whole numbers, fractions, decimals, ratio, proportion, and percentages. The appropriate use of English/metric conversions, exponents, square roots, basic graph interpretation, and basic algebraic expression (formulas) manipulation will be presented. In addition, the solution of geometric figures will be addressed. An introduction to the use of trigonometry for the solution of right and oblique triangles will also be included.

Upon successful completion of this course, students should be able to:

Conduct arithmetic operations using whole numbers, fractions, and decimals for the solutions of typical technologically based concepts, processes and operations.
Perform English and Metric computations involving numeric and literal problems.
Demonstrate the use of a Cartesian and a polar coordinate system to interpret and construct basic graphs, such as; bar, pie, broken line, etc.
Analyze data and select an appropriate method to construct a chart, or graph, as well as decipher relationships among topical data.
Solve fundamental expressions and common formulas using algebraic rules for addition, subtraction, multiplication, division, ratio, proportion, percentages, powers and roots, and transposition of terms, to include mixed operators.
Apply appropriate terminology and rules for solving problems involving basic geometric entities and figures.
Communicate the rules of similarity and congruency and solve basic triangles.
Identify and construct right triangles and utilize the Pythagorean theory, sine, cosine, and tangent functions and The Law of Sines/Cosines for the trigonometric solution of unknowns.
