    What is cot 48°?

    Answer

    cot 48° ≈
    0.9004

    Angle in radians: 48° = 4π/15. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. An exact form of cot 48° in square roots exists, but it is unwieldy — nested radicals.

    cot 48° = cos 48° / sin 48° ≈ 0.9004

    xyOP

    P(cos 48°, sin 48°) ≈ (0.6691, 0.7431)

    C(cot 48°, 1) ≈ (0.9004, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 48°?

    cot 48° ≈ 0.9004

    Is there an exact value of cot 48°?

    Yes: 48° 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 48° ≈ 0.9004.

    Why does a calculator show 0.8332 for cot 48?

    The calculator is in radian mode (RAD): it takes cot 48 as the cotangent of 48 radians, cot 48 rad ≈ 0.8332. Switch it to degrees (DEG): cot 48° ≈ 0.9004. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
