In-class task TODAY. See sheet for details. You must have your own graphics calculator.
Week 5 - Tuesday
We're going to collect data for our assignment today.
Extra data to practice fitting a curve to is at right. Also link below pages 3 & 11 have data to fit. Try both by calculator and by hand.
Week 5 - Monday
