Homework Statement
This is a problem within a problem. I need to differentiate the area of a chord of find the maximum area (and hopefully, in the process, radius).
Homework Equations
I found this equation on another site:
A=R^2[(Pi/180*c - sin c)]/2
Where:
• C is the central angle in degrees.
• R is the radius of the circle of which the segment is a part.
• A is the area of the chord.
(I think I typed it out correctly. Here's the website: http://www.mathopenref.com/segmentarea.html)
The Attempt at a Solution
First problem: How can I differentiate the equation when the is denominator is 2? My central angle is 180 Degrees, so it worked out to be:
A=R^2[(Pi - sin 180)]/2
Something is terribly wrong, I'm sure. Is it even the right formula? There is also this formula:

Sorry it's a little messy, but my thought pattern is crazy at the moment. Thanks for any help.
