Cotangent Calculator

Your details

Enter the angle. For degrees use any real number (e.g. 45), for radians (e.g. 1.5708), for multiples of pi enter the coefficient (e.g. 0.25 for pi/4).

cot(45 degrees) = 1

  • Cotangent is positive in the first quadrant (0 to 90 degrees).
  • cot(x) = cos(x) / sin(x) = 0.707107 / 0.707107 = 1.
  • The tangent (reciprocal) is tan(x) = 1.
  • The cotangent function has a period of pi (180 degrees), repeating the same value every half turn.

Next stepTo find the angle from a known cotangent value, use the arccotangent function: x = arccot(value) = arctan(1/value).
