STANDARD G.C.B.5 Derive using similarity the fact that the length of
the arc intercepted by an angle is proportional to the radius, and
define the radian measure of the angle as the constant of
proportionality; derive the formula for the area of a sector.
Radian introduced only as unit of measure. |
