RADIANS(a)
- where is an angle in degrees.
is an angle in degrees.RADIANS() converts the angle in degrees to angle in radians.
Description
- One radian is the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle.
- The radian is represented by symbol rad.
- Formula for converting from degrees to radians is :
Angle in radians = angle in degrees x Failed to parse (syntax error): {\displaystyle \frac{\pi}{180 °}}
- If argument is non-numeric, Calci returns a NaN error.
- RADIANS() can be used for array of angles e.g. 0 to 90 degress in steps of 15 degrees as -
