it is 1/2 as in that range the value of x hovers from 0 to 1 n back to 0 in a sinusoidal form

The sinusoidal graphic from [0,180] were moved and get the result is 0 to 1 and back to 0 again.
So the average value is 1/2.

sin 0 = 0
sin 90 = 1
sin 180 = 0
periodic function
=> average value of f = 1/2

. . . . . . 180
(1/180)â«sin(x)dx = (- cos(180) + cos(0))/180 =
. . . . . . 0
(1 + 1)/180 = 2/180
Usually, x is expressed in radians, and the average sought is 2/Ï â 0.63662
