Law of Sines: The Ambiguous Case

Explanation (algebraic and geometric), interactive tutorial

Law of Sines: The Ambiguous Case

Sketchpad and flash tutorials

Law of Sines

Law of Sines applet….. click on red rectangle

--------------------------------

sin, cos, and tan function boxes - put in degrees and the sin, cos, or tan value comes out. Box goes right to left (very cool… shows angle, then coordinate) good way to explain how “tangent” relates to the word “tangent” learned in geometry.

Graphs of y=sin(x), y=cos(x), and y=tan(x) – shows how unit circle and the graphs are related

Graph of y=sin(bx) – shows and explains how the period is changed. Allows you to change 'b'

Graph of y=a sin b(x-c). See graph of y=sin x and y=a sin b(x-c). Change a, b, and c and see how it changes

Graphic explanations of the Law of Sines and Law of Cosines
