    Cot 16 Degrees

    Sin, Cos, Tan, Cot of an Angle
    Function
    Angle (°)

    What is cot 16°?

    Answer

    cot 16° ≈
    3.4874

    Angle in radians: 16° = 4π/45. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 16° can't be written with square roots: 16° is not a multiple of 3°.

    cot 16° = cos 16° / sin 16° ≈ 3.4874

    xyOP

    P(cos 16°, sin 16°) ≈ (0.9613, 0.2756)

    C(cot 16°, 1) ≈ (3.4874, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

    FAQ

    What is cot 16°?

    cot 16° ≈ 3.4874

    Why does cot 16° 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°. 16° is not, so no such exact form exists; the value is used as a decimal: cot 16° ≈ 3.4874.

    Why does a calculator show 3.3263 for cot 16?

    The calculator is in radian mode (RAD): it takes cot 16 as the cotangent of 16 radians, cot 16 rad ≈ 3.3263. Switch it to degrees (DEG): cot 16° ≈ 3.4874. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
