    Angle (°)

    What is cot 86°?

    Answer

    cot 86° ≈
    0.0699

    Angle in radians: 86° = 43π/90. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 86° can't be written with square roots: 86° is not a multiple of 3°.

    cot 86° = cos 86° / sin 86° ≈ 0.0699

    xyOP

    P(cos 86°, sin 86°) ≈ (0.0698, 0.9976)

    C(cot 86°, 1) ≈ (0.0699, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 86°?

    cot 86° ≈ 0.0699

    Why does cot 86° 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°. 86° is not, so no such exact form exists; the value is used as a decimal: cot 86° ≈ 0.0699.

    Why does a calculator show 0.4155 for cot 86?

    The calculator is in radian mode (RAD): it takes cot 86 as the cotangent of 86 radians, cot 86 rad ≈ 0.4155. Switch it to degrees (DEG): cot 86° ≈ 0.0699. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
