    Cot 1 Degree

    Sin, Cos, Tan, Cot of an Angle
    Function
    Angle (°)

    What is cot 1°?

    Answer

    cot 1° ≈
    57.2900

    Angle in radians: 1° = π/180. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 1° can't be written with square roots: 1° is not a multiple of 3°.

    cot 1° = cos 1° / sin 1° ≈ 57.2900

    xyOP

    P(cos 1°, sin 1°) ≈ (0.9998, 0.0175)

    C(cot 1°, 1) ≈ (57.2900, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

    FAQ

    What is cot 1°?

    cot 1° ≈ 57.2900

    Why does cot 1° have no exact value?

    A trigonometric value of a whole number of degrees can be written with square roots only when the angle is a multiple of 3°. 1° is not, so no such exact form exists; the value is used as a decimal: cot 1° ≈ 57.2900.

    Why does a calculator show 0.6421 for cot 1?

    The calculator is in radian mode (RAD): it takes cot 1 as the cotangent of 1 radian, cot 1 rad ≈ 0.6421. Switch it to degrees (DEG): cot 1° ≈ 57.2900. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
