RADIANS(a)

• where $a$ 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 (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \frac{\pi}{180 °}}

• If argument $a$ is non-numeric, Calci returns a NaN error.
• RADIANS() can be used for array of angles from 0 to 90 degress in steps of 15 degrees as -
