A course primarily designed for students preparing for calculus and related disciplines. This course explores trigonometric functions and their applications as well as the language and measurement of angles, triangles, circles, and vectors. These topics will be explored symbolically, numerically, and graphically in real-life applications and interpreted in context. This course emphasizes skill building, problem solving, modeling, reasoning, communication, connections with other disciplines, and the appropriate use of present-day technology.

At the end of this course, students will be able to:

- Translate among various systems of measure for angles including radians, degrees, and revolutions.
- Represent, manipulate, and evaluate trigonometric expressions in terms of sides of a right triangle and in terms of the coordinates of a unit circle.
- Graph, transform, and analyze trigonometric functions using amplitude, shifts, symmetry, and periodicity.
- Manipulate trigonometric expressions and prove trigonometric identities.
- Solve trigonometric equations using inverses, periodicity, and identities.
- Define, represent, and operate with vectors both geometrically and algebraically.
- Apply the law of sines and the law of cosines to determine lengths and angles.
- Use variables, trigonometric functions, and vectors to represent quantities, create models, find solutions, and communicate an interpretation of the results.
- Determine the reasonableness and implications of mathematical methods, solutions, and approximations in context.

Equivalent placement test scores also accepted. IRW115 may be taken in place of (WR115 and RD115).

Recommended: MTH 111 taken within the past 4 terms.
