    Course Introduction
    This Trigonometry [CMAT 1223] course adheres to the scope and sequence of a one-semester Trigonometry course. The course description provided is the from the statewide common course information.

    Course Description: Trigonometric functions and graphs; inverse trigonometric functions; fundamental identities and angle formulas; solving equations; triangles with applications; polar coordinate system.

    Upon successful completion of this course, the student will be able to:

    1. Apply the definitions of angles, triangles, and the rectangular coordinate system to the six trigonometric functions.
    2. Solve problems using right triangle trigonometry.
    3. Extending the six trig functions on each quadrant by defining a reference angle with + - signs.
    4. Solve problems for arc length and area of a sector.
    5. Calculate linear and angular speed to solve related problems.
    6. Graph trigonometric functions and their transformations.
    7. Solve problems involving the inverses of trigonometric functions.
    8. Verify trigonometric identities and solve problems involving sum, difference, double-angle, half-angle, sum-to-product, and product-to-sum formulas.
    9. Solve trigonometric equations.
    10. Solve triangles and applications using the Laws of Sines, the Law of Cosines and area formulas.
    11. Plot points and rewrite equations between the rectangular and polar coordinate systems.
    12. Apply the De Moivre’s and nth root Theorems
