Lessons for F.TF.B.5
Amplitude and reflectionHalf the distance between the highest and the lowest value of a wave.Lesson
Modeling things that repeatUsing a sine or cosine model for any quantity that rises and falls on a steady cycle.Lesson
Periodic functionsOne full repetition of the pattern is a cycle and its width along the input axis is the period.Lesson
Finding the period from the equationReading how much a wave is squeezed or stretched sideways from the coefficient on the input.Lesson
Tides, daylight and soundDescribing the height of water at a harbor as a wave with a period of about half a day.Lesson
Midline and vertical shiftMoving the whole wave up or down, which moves the midline without changing the amplitude.Lesson
Writing an equation from a waveReading the amplitude, midline, period and shift off a picture and assembling the matching formula.Lesson
