Secant Calculator - sec(x)

Your details

Forward: enter an angle, get sec(x). Inverse: enter a secant value, get the angle.
Enter the angle whose secant you want. Undefined at 90 deg, 270 deg, etc.

sec(60 deg) = 2.000000

  • sec(x) = 1 / cos(x) = 1 / 0.500000 = 2.000000.
  • The secant is always positive (>= 1), because |sec(x)| >= 1 for all defined angles.
  • The exact form for this special angle is 2.
  • Your angle normalises to 60.00 deg in the principal cycle 0-360 deg.

Next stepUse the inverse mode (arcsec) to go back from a secant value to the angle.
