What is circular system of angle measure?
What is circular system?
In circular system angle is measured in Radians (Real numbers).
RADIAN
Angle subtended on the center by an arc whose
length is equal to the radius of circle is said to be
one or one radian.
Length of Arc=Radius of circle
l = r
Angle subtended on center=1
Remember: As and both measured in same units, for this reason this
angle measure is unit-less. It is a real number.
