The table at right shows measurements made on a circle with a one-meter radius. Each entry in the s-column is an arc length,and the adjacent entry in the c-column is the corresponding chord length, both in meters. Explain why c < s, and determine the range of values for c and for s. With s on the horizontal axis and c on the vertical axis, sketch an approximate graph of
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.

We 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
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.
