    Angle (°)

    What is cot 88°?

    Answer

    cot 88° ≈
    0.0349

    Angle in radians: 88° = 22π/45. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 88° can't be written with square roots: 88° is not a multiple of 3°.

    cot 88° = cos 88° / sin 88° ≈ 0.0349

    xyOP

    P(cos 88°, sin 88°) ≈ (0.0349, 0.9994)

    C(cot 88°, 1) ≈ (0.0349, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 88°?

    cot 88° ≈ 0.0349

    Why does cot 88° 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°. 88° is not, so no such exact form exists; the value is used as a decimal: cot 88° ≈ 0.0349.

    Why does a calculator show 28.2322 for cot 88?

    The calculator is in radian mode (RAD): it takes cot 88 as the cotangent of 88 radians, cot 88 rad ≈ 28.2322. Switch it to degrees (DEG): cot 88° ≈ 0.0349. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
