This is an application of sine functions using biorhythms as the context. The interest is high as students create their own personal & real biorhythm. Period and translations of circular functions are addressed using the Calculator and Graphs & Geometry applications.
Before the Activity
This is an application of the sine curve hence students should have a basic understanding of amplitude, period and translations of sine graphs.
During the Activity
Students can follow through the worksheet with teacher guidance. The teacher will need to discuss with the students how a given period is written into the sine function. Also guidance on the horizontal translation will be necessary.
