    Angle (°)

    What is cot 55°?

    Answer

    cot 55° ≈
    0.7002

    Angle in radians: 55° = 11π/36. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 55° can't be written with square roots: 55° is not a multiple of 3°.

    cot 55° = cos 55° / sin 55° ≈ 0.7002

    xyOP

    P(cos 55°, sin 55°) ≈ (0.5736, 0.8192)

    C(cot 55°, 1) ≈ (0.7002, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 55°?

    cot 55° ≈ 0.7002

    Why does cot 55° 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°. 55° is not, so no such exact form exists; the value is used as a decimal: cot 55° ≈ 0.7002.

    Why does a calculator show −0.0221 for cot 55?

    The calculator is in radian mode (RAD): it takes cot 55 as the cotangent of 55 radians, cot 55 rad ≈ −0.0221. Switch it to degrees (DEG): cot 55° ≈ 0.7002. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
