Trigonometric Graphs, Identities, and Equations Advanced AlgebraChapter 14
The functions of sine an cosine shard the following: • The domain of each function is all real numbers • The range of each function is • Each function is periodic • Each graph has a repeating portion called a cycle • 1 period of a graph is 1 full cycle • Amplitude is the defined as the height of the graph from it’s center • ½ it’s total height • Amplitude is always positive
Sine • Period: • Amp:
Cosine • Period: • Amp:
Graphing Functions • For the trig functions and • If a is positive: Graph opens “normal” • If a is negative: Graph opens “opposite”
Translations • To obtain the graph of ortransform the graph of oras follows: • Vertical shift • Shift the graph k units vertically • Horizontal shift • Shift the graph h units horizontally • Reflection • If a is less than zero, flip graph over x-axis
