Translations of Trigonometric Graphs Translation of a Sine Function Amplitude Period
Translations of Trigonometric Graphs Translation of a Sine Function Amplitude Period Moving a graph left or right is called a phase shift.
Amplitude Phase shift Vertical shift Period You can combine the transformations of trigonometric functions. Use the values of a, b, h, andkto identify the important features of a sine or cosine function. y =asinb(x–h)+k
