An angle measuring based on radian size is based on the supposition that:
"one radian = the magnitude of the optic corner of a circle bounded past times a round down arc equal inwards length to the radius"
If OA in addition to OB are radius = r in addition to arc AB is besides the length r in addition to thence ∠AOB is 1 radian. Generally nosotros already know that 1 plough = 360º in addition to the circumference of the circle k = 2πr, in addition to thence based on the comparing formula on the circle is valid:
So the means to alter degrees to radians is essentially based on the radian equation alongside the next degrees:
3.14 radians = 180º
1 radian = 57.3º
Example :
How much is 30º!
Answer:
So 30º = 0.524 radians.
Similarly this article.
Sorry if at that topographic point is a incorrect word.
