Description
Question No. 4 , Question No. 5 , Question No. 6
This is defining relation of measure of angle in circular system.
This is ratio between length of arc and radius of circle.
As length of arc and radius will be in same unit, so this angle measure will be unitless i.e. angle is measured as real number.
If in a problem, angle will be given in some other measure (unit), first we will convert it to circular(radian) measure.
Remember: This relation is only valid for circular(radian) measure of angle.
