Re: sine and QPro

[Pete Lohstreter <petel@tenet.edu>]

In the past, I have had the students change the degree value to radians 
first and then do the operation.  I recently obtained Excel 5.0 and it 
handles either degrees or radians. 

ex.  Sin (2*pi*degrees/360)  will give you the expected results.
     For your 30 degree example, the problem becomes Sin (pi/6) = 0.5
