any good websites that explains everything about radians for gr12 math?

  • math -

    There is not a lot to explain.

    1 radian = 180/pi degrees = 57.296 degrees

    An angle measured in radians equals the ratio of the arc length of a sector of a circle subtended by that angle, divided by the radius of the circle.
