    Angle (°)

    What is cot 19°?

    Answer

    cot 19° ≈
    2.9042

    Angle in radians: 19° = 19π/180. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 19° can't be written with square roots: 19° is not a multiple of 3°.

    cot 19° = cos 19° / sin 19° ≈ 2.9042

    xyOP

    P(cos 19°, sin 19°) ≈ (0.9455, 0.3256)

    C(cot 19°, 1) ≈ (2.9042, 1) — where line OP meets the line y = 1; C is beyond the drawing, the arrow points to it.

    FAQ

    What is cot 19°?

    cot 19° ≈ 2.9042

    Why does cot 19° 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°. 19° is not, so no such exact form exists; the value is used as a decimal: cot 19° ≈ 2.9042.

    Why does a calculator show 6.5968 for cot 19?

    The calculator is in radian mode (RAD): it takes cot 19 as the cotangent of 19 radians, cot 19 rad ≈ 6.5968. Switch it to degrees (DEG): cot 19° ≈ 2.9042. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
