Currently Teaching

NMTH-220
3 Credits
Topics include the trigonometric ratios, radian measure, angles in a coordinate system, ratio values for special angles, trigonometric inverses, graphs of trigonometric functions, and trigonometric identities and equations
NMTH-275
3 Credits
Topics from precalculus mathematics are studied with an emphasis on functions and graphs. Topics include the algebra of functions and the study of inverse functions. Rational, exponential, logarithmic and piecewise-defined functions are among those studied. Students, who earn credit for NMTH-275, cannot take NMTH-260 or NMTH-272.
NMTH-180
3 Credits
An introductory algebra course consisting of a blended lecture/lab component in which the basics of evaluating algebraic expressions, solving linear equations and inequalities and graphing linear functions are studied. The Pythagorean Theorem and systems of linear equations are also studied. Students cannot earn credit for both NMTH-180 and NMTH-245.
NMTH-206
3 Credits
Students will study right triangle trigonometry with an emphasis on concepts and applications related to computer integrated machining technology (CIMT). Topics include trigonometric ratios in right triangles, coordinate geometry calculations, circle properties, simple and complex machine applications, and 3-D coordinate geometry.
