    Cot 17 Degrees

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

    What is cot 17°?

    Answer

    cot 17° ≈
    3.2709

    Angle in radians: 17° = 17π/180. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 17° can't be written with square roots: 17° is not a multiple of 3°.

    cot 17° = cos 17° / sin 17° ≈ 3.2709

    xyOP

    P(cos 17°, sin 17°) ≈ (0.9563, 0.2924)

    C(cot 17°, 1) ≈ (3.2709, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

    FAQ

    What is cot 17°?

    cot 17° ≈ 3.2709

    Why does cot 17° 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°. 17° is not, so no such exact form exists; the value is used as a decimal: cot 17° ≈ 3.2709.

    Why does a calculator show 0.2862 for cot 17?

    The calculator is in radian mode (RAD): it takes cot 17 as the cotangent of 17 radians, cot 17 rad ≈ 0.2862. Switch it to degrees (DEG): cot 17° ≈ 3.2709. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
