1. MTH 112 Elementary Functions (aka: Trigonometry) Review for the Final

2. Two Parts  Part I (54 pts) – No calculators. – Just you, the test, and a pen or pencil.  Part II (53 pts) – Calculators may be used. – Be careful with radians vs. degrees!  Extra Credit! – Since the total is 107 pts, the extra 7 points will be considered extra credit.

3. Part I (54 pts)  The unit circle (8 pts)  Values of trigonometric and inverse trigonometric functions (14 pts)  Graphs of the trigonometric functions (13 pts) – f(x) = sin x f(x) = cos x f(x) = tan x – f(x) = Asin(Bx-C)+D f(x) = Acos(Bx-C)+D  Identities (8 pts)  Graphs of Polar Equations (4 pts)  Other (7 pts) – Given a trig value of an angle, find the others. – Degrees  Radians – Coterminal Angles & Reference Angles

4. Part II (53 pts)  Solve Triangles (30 pts) – Right & oblique triangles – Related applications  Simplifying Expressions (4 pts)  Solving Equations (9 pts)  Polar Coordinates & Equations (10 pts) – Polar  Rectangular Conversions – Multiple representations of the same point
