c vs s.

s c

0.256 0.255

0.618 0.608

1.234 1.157

1.571 1.414

1.896 1.625

Then.(Continuation)Express s and c in terms of è, the central angle that intercepts s and c. Combine these equations to express c as a function of s. Graph this relationship.

**drwls**, Saturday, April 17, 2010 at 1:23pmWe can't draw graphs for you. You have the data to draw one yourself.

Is your symbol è supposed to be theta? Let's just call it angle A. I will assume it is in radians.

The arc length is

s = Radius*A = A

The chord length is

c = 2 R sin (A/2) = 2 sin (A/2)

c = 2 sin (s/2)

The data in the table fits that equation well.
