Biorhythms

An interactive excel worksheet that uses the transformation of a sine graph as a fun activity involving biorhythms. Suitable for AS Maths - Core 2 Microsoft Excel is a spreadsheet package, designed to manipulate and view numerical data such as statistics. You will need to allow macros to run when using most of the sheets available here. This can be checked by opening Excel and clicking Tools Macros Security and choosing Medium or Low security. Also, some sheets require you have Analysis ToolPak installed - this is found by clicking Tools Add ins (you may need the original MS Office disks to do this).
