Finding the Equation of a Sine Curve Using Biorhythm Graphs

This project is good activity to do when discussing how to obtain the equation of a sine curve from a graph. It helps students to see a real life application of the lesson.  It also teaches them how to use technology to obatain the equations and accuracy of calculations.
