    Angle (°)

    What is cot 38°?

    Answer

    cot 38° ≈
    1.2799

    Angle in radians: 38° = 19π/90. The point of the angle is in quadrant I, where cotangent is positive.

    ≈ — rounded to 4 decimal places. cot 38° can't be written with square roots: 38° is not a multiple of 3°.

    cot 38° = cos 38° / sin 38° ≈ 1.2799

    xyOP

    P(cos 38°, sin 38°) ≈ (0.7880, 0.6157)

    C(cot 38°, 1) ≈ (1.2799, 1) — where line OP meets the line y = 1.

    FAQ

    What is cot 38°?

    cot 38° ≈ 1.2799

    Why does cot 38° 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°. 38° is not, so no such exact form exists; the value is used as a decimal: cot 38° ≈ 1.2799.

    Why does a calculator show 3.2226 for cot 38?

    The calculator is in radian mode (RAD): it takes cot 38 as the cotangent of 38 radians, cot 38 rad ≈ 3.2226. Switch it to degrees (DEG): cot 38° ≈ 1.2799. In radians the value is never undefined: π is irrational, so a whole number of radians never lands exactly on an axis.
