In-class group activity 7:  Normalizing a wave function

Open a Microsoft Word document to keep a log of your results and conclusions.   

The wave function ψ(x,0) = cos(x) for x between -π/2 and +π/2 and ψ(x) = 0 for all other x can be normalized. 
You can show this by opening the linked spreadsheet
It has a column for x an a column for ψ(x,0) = N*cos(x) for x between -π and +π with N = 1 initially.  The maximum value of ψ(x,0) is 1.
