    What is cot 57°?

    Answer

    cot 57° ≈
    0.6494

    Angle in radians: 57° = 19π/60. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. An exact form of cot 57° in square roots exists, but it is unwieldy — nested radicals.

    cot 57° = cos 57° / sin 57° ≈ 0.6494

    xyOP

    P(cos 57°, sin 57°) ≈ (0.5446, 0.8387)

    C(cot 57°, 1) ≈ (0.6494, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 57°?

    cot 57° ≈ 0.6494

    Is there an exact value of cot 57°?

    Yes: 57° is a multiple of 3°, and the values of such angles can be written with square roots — but the expression is unwieldy, with nested radicals built from the values of 18° and 15° (3° = 18° − 15°). In practice the decimal is used: cot 57° ≈ 0.6494.

    Why does a calculator show 2.0631 for cot 57?

    The calculator is in radian mode (RAD): it takes cot 57 as the cotangent of 57 radians, cot 57 rad ≈ 2.0631. Switch it to degrees (DEG): cot 57° ≈ 0.6494. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
