    Angle (°)

    What is cot 215°?

    Answer

    cot 215° ≈
    1.4281

    Angle in radians: 215° = 43π/36. The point of the angle is in quadrant III, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 215° can't be written with square roots: 215° is not a multiple of 3°.

    cot 215° = cot(180° + 35°) = cot 35° ≈ 1.4281

    cot 215° = cos 215° / sin 215° ≈ 1.4281

    xyOP

    P(cos 215°, sin 215°) ≈ (−0.8192, −0.5736)

    C(cot 215°, 1) ≈ (1.4281, 1) — where line OP meets the line y = 1, on the extension of the ray beyond O (dashed).

    FAQ

    What is cot 215°?

    cot 215° ≈ 1.4281

    Why does cot 215° 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°. 215° is not, so no such exact form exists; the value is used as a decimal: cot 215° ≈ 1.4281.

    Why does a calculator show 0.2018 for cot 215?

    The calculator is in radian mode (RAD): it takes cot 215 as the cotangent of 215 radians, cot 215 rad ≈ 0.2018. Switch it to degrees (DEG): cot 215° ≈ 1.4281. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
