    Cot 11 Degrees

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

    What is cot 11°?

    Answer

    cot 11° ≈
    5.1446

    Angle in radians: 11° = 11π/180. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 11° can't be written with square roots: 11° is not a multiple of 3°.

    cot 11° = cos 11° / sin 11° ≈ 5.1446

    xyOP

    P(cos 11°, sin 11°) ≈ (0.9816, 0.1908)

    C(cot 11°, 1) ≈ (5.1446, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

    FAQ

    What is cot 11°?

    cot 11° ≈ 5.1446

    Why does cot 11° 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°. 11° is not, so no such exact form exists; the value is used as a decimal: cot 11° ≈ 5.1446.

    Why does a calculator show −0.0044 for cot 11?

    The calculator is in radian mode (RAD): it takes cot 11 as the cotangent of 11 radians, cot 11 rad ≈ −0.0044. Switch it to degrees (DEG): cot 11° ≈ 5.1446. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
