MySQL RADIANS() function

RADIANS() function

MySQL RADIANS() converts the value of a number from degrees to radians. (pi radians equals to 180 degrees).

This function is useful in -

  • In scientific modeling and simulations, angles are commonly represented in radians.
  • This is especially true in fields like physics, astronomy, and engineering, where precise angular measurements are required.
  • The RADIANS() function ensures that the angles are in the correct unit for accurate results.
  • Functions like sine, cosine, and tangent in MySQL's mathematical functions library expect angles to be in radians.
  • The RADIANS() function is crucial for ensuring the correct input format for these functions.
  • In navigation and GPS systems, angles are typically represented in radians. The RADIANS() function helps in converting angles from degrees to radians.
  • In computer graphics and visualization, radians are often used to represent angles.
