Determine the period of this function. http://media.education2020.com/EVresources/648-14-11-00-00_files/i0260000.jpg
go from lowest point to lowest point how long an interval is that?
or for that matter from highest point to highest point? same length
Thank you! So when asked that again just determine the length of the interval from highest to highest point (or lowest to lowest)
notice that if you went from one zero to the next it will not work, but would if you went twice you are really suppose to visualize over what length the function goes before it repeats
The definition of a "period" is the time it takes to go through one complete cycle, so from peak-to-peak or from any point to any point that will give you one complete copy of the graph.
