Question

Define radian and relation between radian and degeee ?​

Answer 1

Answer:

Radian - an angle subtended at the center of a circle by an arc whose length is equal to the radius of the circle is callled one radian.

Relation between radian and degree :-

when a body or a particle completes one rotation, (360°) and distance travelled (circumference of a circle).

$= > \frac{2\pi \: r}{r}$

360° = 2π radian

$= > 1rad = \frac{360}{2 \times \pi} = \frac{180}{22} \times 7$

Thus,

$= > 1 \: \: radian = 57.27$

Answer 2

Answer:

It follows that the magnitude in radians of one complete revolution (360°) is the length of the entire circumference divided by the radius, or 2πr / r, or 2π. Thus 2π radians is equal to 360°, meaning that one radian is equal to 180/π degrees. The relation can be derived using the formula of arc length.
