Degrees is a unit of measurment of angle of inclination, so is radiansand so is grades.

Radians is used at the unit for higher studies.

1 radian is equal to approximately 57 degrees.

1 pi is equal to 180 degrees.

In calculus, or trigo functions are in radians, there is no reason for that, they just are.. its like asking your school teacher why all angles are in degrees.

1)A radian is the unit of measurement of an angle other than degrees.

2)Because when we calculate anything in physics or any other subjects we cannot use degree term with numbers so radian is used.

3)because degree is not sutable for the functions.
